* ALSA: core: Follow standard EXPORT_SYMBOL() declarationsTakashi Iwai2017-06-161-3/+0
| | | | | | | | | | Just a tidy up to follow the standard EXPORT_SYMBOL*() declarations in order to improve grep-ability. - Move EXPORT_SYMBOL*() to the position right after its definition - Remove superfluous blank line before EXPORT_SYMBOL*() lines Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: core: Use standard printk helpersTakashi Iwai2014-02-141-1/+1
| | | | | | | Use dev_err() & co as much as possible. If not available (no device assigned at the calling point), use pr_xxx() helpers instead. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | script/kernel-doc reports the following type of warnings (when run in verbose mode): Warning(sound/core/init.c:152): No description found for return value of 'snd_card_create' To fix that: - add missing descriptions of function return values - use "Return:" sections to describe those return values Along the way: - complete some descriptions - fix some typos Signed-off-by: Yacine Belkadi <yacine.belkadi.1@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker2011-10-311-0/+1
| | | | | | | | These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* ALSA: snd_dma_pointer workaround for chipsets with buggy DMAKrzysztof Helt2009-10-111-1/+9
| | | | | | | | | | | | | | | | | | | The chipsets with the isa_dma_bridge_buggy set do not stop DMA during DMA counter reads. The DMA counter is read in two 8-bit read steps on x86 platform. Sometimes, such reads happen during higher byte change so the lower byte is already decremented (rolled over) but the higher byte is not. It introduces an error that position is moved 256 bytes ahead of the true position. Thus, the next DMA position read can return a lower value then the previous read. If the DMA position is decreased (reversed) the ALSA subsystem is tricked into the playback underrun error and resets the playback. It results in a "pop" during a playback. Work around the issue by reading the counter twice and choosing a higher value. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] Remove sound/driver.hTakashi Iwai2008-01-311-1/+0
| | | | | | | | | | | | This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
