Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux

Pull fbdev changes from Tomi Valkeinen:
 "Nothing particularly stands out in this pull request.  The biggest
  part of the changes are cleanups.

  Maybe one fix to mention is the "fb: reorder the lock sequence to fix
  potential dead lock" which hopefully fixes the fb locking issues
  reported by multiple persons.

  There are also a few commits that have changes to arch/arm/mach-at91
  and arch/avr32, which have been acked by the maintainers"
