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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJSg2oCAAoJEPo9qoy8lh71vXsP/2AjkzOlcKBPutMG/W30QMHT tkKfr/RL8C3oXcimkE6ch3ksbFj2t5corxa/DLTdESdTpeFAgxj72pcdhN3X4+Xs 7IokExM2W5s6p4pP66PTr2A5XhEyAHtEMp+2JbHPRzwZitblzBLZvuPUJljwJDpj Z9+sD00xv/MZrXDCsEN8k2xdJ3rFn6JgX267y1qajlsocZoseTF2ed94IN/YnIM7 B2hra1B4E21FPYLzRDOJRmZa0YGomLTymezPnPg33hLBhnJU/aG4HLDHKUZWhduz /6UwACH63ja7I2z/8AZHQ1ACdbGheRtHbjwV9LLYlbaAvPmUqNTZ4b6UeQOb/EZ0 3SPCYbwD6+RMhSx/j/XhySvw82RY0i1aTlTDyjgOggfrfdi4x1Wk54bUWp5l9O3D SX1vSpNLGSh4GKXRzJjf3jouG/LcOzlpDlVZXzgsPzkyirluUv6QdMTopJwFwIGx rFgtsbkvhEsFvaNhhVIqQXKfwZ69r42U5JC+fDM5u7VX0mqyJ1usUNGvNSeifcDg EwUAI6RGnOXCO6crj2BZYpRTdc61tnY9b4CGLHDCeQkEXokEsEJ7Mz+8YfSwFo7X wqh+dAPQaixeHtUFZ8GhHXeAsjoQRSBXygf3NSNmCeP3WsmuozbauuujSrrTHITp LOXFPhU9uxHu4mDd6wrq =59+j -----END PGP SIGNATURE----- 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.
