Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
"First round of updates for the input subsystem.
You will get a new touchsreen driver for Cypress 4th generation
devices, a driver for a special controller implementing PS/2 protocol
in OLPC devices, and a driver for power key for SiRFprimaII PWRC.
HID and bcm5497 now support for the 2013 MacBook Air.
EVIOCGKEY and the rest of evdev ioctls now flush events of matching
type from the client's event queue so that clients can be sure any
events received after issuing EVIOCG* ioctl are new events.
And a host of cleanups and improvements in other drivers"
