Due to there being some AC97 MFD there's a few fairly large changes in input and the MFD layer, mainly to the wm97xx driver. There's also some drivers/drm changes to support the new AMD Stoney platform, these are shared with the DRM subsystem and should be being merged via both. Within the subsystem the overwhelming bulk of the changes is in the Intel drivers which continue to need lots of cleanups and fixes, this release they've also gained support for their open source firmware. There's also some large changs in the core as Morimoto-san continues to mirror operations into the component level in preparation for conversion of drivers to that. - The AC97 bus has finally caught up with the driver model thanks to some dedicated and persistent work from Robert Jarzmik. - Continued work from Morimoto-san on moving us towards being able to use components for everything. - Lots of cleanups for the Intel platform code, including support for their open source audio firmware. - Support for scaling MCLK with sample rate in simple-card. - Support for AMD Stoney platform.
| * License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-025-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

* | ALSA: sb: Minor optimization / fix of timer usage in sb8_midi.cTakashi Iwai2017-10-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the SB8 MIDI code sets up the timer object at each time before scheduling it at trigger callback, but basically this is superfluous once after set up. Also, the code misses the del_timer_sync() call that may leave a race condition for use-after-free. This patch addresses these issues, moving timer_setup() to snd_sb8dsp_midi(), and adding the del_timer_sync() call at snd_sb8dsp_midi_output_trigger() to make sure.

| * | | sched/wait: Rename wait_queue_t => wait_queue_entry_tIngo Molnar2017-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename: wait_queue_t => wait_queue_entry_t 'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue", but in reality it's a queue *entry*. The 'real' queue is the wait queue head, which had to carry the name. Start sorting this out by renaming it to 'wait_queue_entry_t'. This also allows the real structure name 'struct __wait_queue' to lose its double underscore and become 'struct wait_queue_entry', which is the more canonical nomenclature for such data types.

* | ALSA: seq: Allow the modular sequencer registrationTakashi Iwai2017-06-123-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many drivers bind the sequencer stuff in off-load by another driver module, so that it's loaded only on demand. In the current code, this mechanism doesn't work when the driver is built-in while the sequencer is module. We check with IS_REACHABLE() and enable only when the sequencer is in the same level of build. However, this is basically a overshoot. The binder code (snd-seq-device) is an individual module from the sequencer core (snd-seq), and we just have to make the former a built-in while keeping the latter a module for allowing the scenario like the above. This patch achieves that by rewriting Kconfig slightly. Now, a driver that provides the manual sequencer device binding should select CONFIG_SND_SEQ_DEVICE in a way as select SND_SEQ_DEVICE if SND_SEQUENCER != n Note that the "!=n" is needed here to avoid the influence of the sequencer core is module while the driver is built-in. Also, since rawmidi.o may be linked with snd_seq_device.o when built-in, we have to shuffle the code to make the linker happy. (the kernel linker isn't smart enough yet to handle such a case.) That is, snd_seq_device.c is moved to sound/core from sound/core/seq, as well as Makefile. Last but not least, the patch replaces the code using IS_REACHABLE() with IS_ENABLED(), since now the condition meets always when enabled. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a slightly intensive rewrite of Kconfig and Makefile about ALSA sequencer stuff. The first major change is that the kconfig items for the sequencer are moved to sound/core/seq/Kconfig. OK, that's easy. The substantial change is that, instead of hackish top-level module selection in Makefile, we define a Kconfig item for each sequencer module. The driver that requires such sequencer components select exclusively the kconfig items. This is more straightforward and standard way. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | ALSA: seq: Allow the tristate build of OSS emulationTakashi Iwai2017-06-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently OSS sequencer emulation is tied with ALSA sequencer core, both are built in the same level; i.e. when CONFIG_SND_SEQUENCER=y, the OSS sequencer emulation is also always built-in, even though the functionality can be built as an individual module. This patch changes the rule and allows users to build snd-seq-oss module while others are built-in. Essentially, it's just a few simple changes in Kconfig and Makefile. Some driver codes like opl3 need to convert from the simple ifdef to IS_ENABLED(). But that's all. You might wonder how about the dependency: right, it can be messy, but it still works. Since we rewrote the sequencer binding with the standard bus, the driver can be bound at any time on demand. So, the synthesizer driver module can be loaded individually from the OSS emulation core before/after it. Signed-off-by: Takashi Iwai <tiwai@suse.de>
