Pull input layer fixes from Dmitry Torokhov:

 - a change to the ALPS driver where we had limit the quirk for
   trackstick handling from being active on all Dells to just a few
   models

 - a fix for a build dependency issue in the sur40 driver

 - a small clock handling fixup in the LPC32xx touchscreen driver

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: alps - only the Dell Latitude D420/430/620/630 have separate stick button bits
  Input: sur40 - add dependency on VIDEO_V4L2
  Input: lpc32xx_ts - fix warnings caused by enabling unprepared clock
