   fbcon locking), add locking checks in vt/console code and make
   assorted cleanups in fbdev and backlight code (Daniel Vetter)

 - add COMPILE_TEST support to atmel_lcdfb, da8xx-fb, gbefb, imxfb,
   pvr2fb and pxa168fb drivers (me)

 - fix DMA API abuse in au1200fb and jz4740_fb drivers (Christoph
   Hellwig)

 - add check for new BGRT status field rotation bits in efifb driver
   (Hans de Goede)

 - mark expected switch fall-throughs in s3c-fb driver (Gustavo A. R.
   Silva)

 - remove fbdev mxsfb driver in favour of the drm version (Fabio
   Estevam)

 - remove broken rfbi code from omap2fb driver (me)

 - misc fixes (Arnd Bergmann, Shobhit Kukreti, Wei Yongjun, me)
