Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull more input updates from Dmitry Torokhov: "The second round of updates for the input subsystem. Updates to ALPS an bfin_roraty drivers and a couple oother fixups" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: psmouse - use IS_ENABLED instead of homegrown code Input: bfin_rotary - introduce open and close methods Input: bfin_rotary - convert to use managed resources Input: bfin_rotary - use generic IO functions Input: bfin_rotary - move pin lists into into platform data Input: bfin_rotary - move platform header to linux/platform_data Input: bfin_rotary - mark suspend and resume code as __maybe_unused Input: bfin_rotary - fix potential oops in interrupt handler Input: ALPS - move v7 packet info to Documentation and v6 packet info Input: ALPS - fix confusing comment in protocol data Input: ALPS - do not mix trackstick and external PS/2 mouse data Input: ALPS - fix trackstick detection on some Dell Latitudes Input: ALPS - consolidate setting protocol parameters Input: ALPS - split protocol data from model info Input: ALPS - make Rushmore a separate protocol Input: ALPS - renumber protocol numbers Input: adi - remove an unnecessary check Input: pxa27x_keypad - remove an unneeded NULL check Input: soc_button_array - use "Windows" key for "Home"
