2014-02-17HID: replace hid_output_raw_report with hid_hw_raw_request for feature requestsBenjamin Tissoires
ret = hid_output_raw_report(A, B, C, HID_FEATURE_REPORT); is equivalent to ret = hid_hw_raw_request(A, B[0], B, C, HID_FEATURE_REPORT, HID_REQ_SET_REPORT); whatever the transport layer is.

2013-07-04HID: wacom: Intuos4 battery charging changesPrzemo Firszt
Intuos4 WL is separately reporting power supply and battery charging status - now hid-wacom is using that information. Previously hid-wacom was wrongly treating "battery charging" bit as "power supply connected". Now it should report battery charging, battery discharging, battery full and power supply status. Intuos4 WL sends reports when is in use (obvious) and when unplugging power supply. If means that if the device is being charged, but it's not being used it will never report "battery full". The same problem happens after the device has been connected, but it's not in use - the battery/ac status will be incorrect. Currently there is no mechanism to ask the device to send a report containing battery/ac status. Signed-off-by: Przemo Firszt <przemo@firszt.eu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-01-03HID: Use module_hid_driver macroH Hartley Sweeten
Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.

2012-09-05HID: remove Paul Walmsley's copyright from places where it shouldn't beJiri Kosina
Paul Walmsley has implemented dynamic quirk handling back in 2007 through commits: 2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c") 8222fbe67c ("USB HID: clarify static quirk handling as squirks") 8cef908235 ("USB HID: add support for dynamically-created quirks") 876b9276b9 ("USB HID: add 'quirks' module parameter") and as such, his copyright rightly belongs to drivers/hid/usbhid/hid-quirks.c file. However when generic HID code has been converted to bus and individual quirks separated out to individual drivers on the bus, the copyright has been blindly transfered into all the tiny drivers, which actually don't contain any of Pauls' copyrighted code.

This changes the wacom_probe function to fail if it cannot register the power_supply devices.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

2010-03-22HID: add sysfs speed attribute for wacom bluetooth tabletPrzemo Firszt
The attribute allows to change reporting speed of tablet from userspace through sysfs file. The attribute is RW, valid values: 0 is low speed, 1 is high speed. High speed is the default setting. Using low speed is a workaround if you experience lag when using the tablet. Signed-off-by: Przemo Firszt <przemo@firszt.eu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
