Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov: - a new driver for Rohm BU21029 touch controller - new bitmap APIs: bitmap_alloc, bitmap_zalloc and bitmap_free - updates to Atmel, eeti. pxrc and iforce drivers - assorted driver cleanups and fixes. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (57 commits) MAINTAINERS: Add PhoenixRC Flight Controller Adapter Input: do not use WARN() in input_alloc_absinfo() Input: mark expected switch fall-throughs Input: raydium_i2c_ts - use true and false for boolean values Input: evdev - switch to bitmap API Input: gpio-keys - switch to bitmap_zalloc() Input: elan_i2c_smbus - cast sizeof to int for comparison bitmap: Add bitmap_alloc(), bitmap_zalloc() and bitmap_free() md: Avoid namespace collision with bitmap API dm: Avoid namespace collision with bitmap API Input: pm8941-pwrkey - add resin entry Input: pm8941-pwrkey - abstract register offsets and event code Input: iforce - reorganize joystick configuration lists Input: atmel_mxt_ts - move completion to after config crc is updated Input: atmel_mxt_ts - don't report zero pressure from T9 Input: atmel_mxt_ts - zero terminate config firmware file Input: atmel_mxt_ts - refactor config update code to add context struct Input: atmel_mxt_ts - config CRC may start at T71 Input: atmel_mxt_ts - remove unnecessary debug on ENOMEM Input: atmel_mxt_ts - remove duplicate setup of ABS_MT_PRESSURE ...
