* HID: corsair: fix control-transfer error handlingJohan Hovold2017-01-131-3/+3
| | | | | | | | | | | | | | Make sure to check for short control transfers in order to avoid parsing uninitialised buffer data and leaking it to user space. Note that the backlight and macro-mode buffer constraints are kept as loose as possible in order to avoid any regressions should the current buffer sizes be larger than necessary.

* HID: corsair: fix DMA buffers on stackJohan Hovold2017-01-131-12/+42
| | | | | | | | | | | | Not all platforms support DMA to the stack, and specifically since v4.9 this is no longer supported on x86 with VMAP_STACK either. Note that the macro-mode buffer was larger than necessary.

* HID: corsair: fix mapping of non-keyboard usagesClément Vuchener2016-02-231-0/+3
| | | | | | | | This fixes a bug where the Volume Up key was ignored because it uses the same usage code as G18. Special Corsair usage codes are in the keyboard page, other pages should be left to the generic driver.

* HID: corsair: Add Corsair Vengeance K90 driverClément Vuchener2015-09-301-0/+673
This patch implements a HID driver for the Corsair Vengeance K90 keyboard. It fixes the behaviour of the keys using incorrect HID usage codes and exposes the macro playback mode and current profile to the user space through sysfs attributes. It also adds two LED class devices controlling the "record" LED and the backlight. Signed-off-by: Clément Vuchener <clement.vuchener@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
