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"
