Merge branch 'for-linus' of master.kernel.org:/pub/scm/linux/kernel/git/dtor/input
* 'for-linus' of master.kernel.org:/pub/scm/linux/kernel/git/dtor/input: (65 commits) Input: gpio_keys - add support for switches (EV_SW) Input: cobalt_btns - convert to use polldev library Input: add skeleton for simple polled devices Input: update some documentation Input: wistron - fix typo in keymap for Acer TM610 Input: add input_set_capability() helper Input: i8042 - add Fujitsu touchscreen/touchpad PNP IDs Input: i8042 - add Panasonic CF-29 to nomux list Input: lifebook - split into 2 devices Input: lifebook - add signature of Panasonic CF-29 Input: lifebook - activate 6-byte protocol on select models Input: lifebook - work properly on Panasonic CF-18 Input: cobalt buttons - separate device and driver registration Input: ati_remote - make button repeat sensitivity configurable Input: pxa27x - do not use deprecated SA_INTERRUPT flag Input: ucb1400 - make delays configurable Input: misc devices - switch to using input_dev->dev.parent Input: joysticks - switch to using input_dev->dev.parent Input: touchscreens - switch to using input_dev->dev.parent Input: mice - switch to using input_dev->dev.parent ... Fixed up conflicts with core device model removal of "struct subsystem" manually. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
