* HID: wacom: Fix invalid power_supply_powers callsPrzemo Firszt2012-02-061-3/+4
| | | | | | | | | | power_supply_powers calls added in 35b4c01e2 ("power_supply: add "powers" links to self-powered HID devices") have to be called after power device is created. This patch also fixes the second call - it has to be "ac" instead of "battery" Signed-off-by: Przemo Firszt <przemo@firszt.eu> Signed-off-by: Chris Bagwell <chris@cnpbagwell.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We shouldn't change the event flags of input devices after they get registered. Otherwise, udev will not get notified of these flags and cannot setup the devices properly. This fixes the probing to set the input event flags on the input_mapped callback instead of the probe function.

* | HID: wacom: Fix error path of power-supply initializationDavid Herrmann2011-09-071-12/+9
|/ | | | | | | | | | | | | | | | power_supply_unregister() must not be called if power_supply_register() failed. The wdata->psy.dev pointer may point to invalid memory after a failed power_supply_register() and hence wacom_remove() will fail while calling power_supply_unregister(). This changes the wacom_probe function to fail if it cannot register the power_supply devices. If we would want to keep the previous behaviour we had to keep some flag about the power_supply state and check it on wacom_remove, but this seems inappropriate here. Hence, we simply fail, too, if power_supply_register fails. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

* HID: wacom: make sysfs permissions more strictJiri Kosina2010-11-181-1/+1
| | | | | | | | | | | | | | It's not really dangerous in this driver, but it's against general practice and worth fixing. Wacom uses the attribute for changing the reporting speed of the tablet (and this actually requires poking the device in the background) (still I wouldn't consider it a security issue though). udev is a proper place to handle this.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Based on the work by Andrew Zabolotny, an HID driver for the Bluetooth Wacom tablet. This is required as it uses a slightly different protocols from what's currently support by the drivers/input/wacom* driver, and those only support USB. A user-space patch is required to activate mode 2 of the Wacom tablet, as hidp does not support hid_output_raw_report.
