Merge branch 'x86-fb-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fb changes from Ingo Molnar: "This tree includes preparatory patches for SimpleDRM driver support, by David Herrmann. They clean up x86 framebuffer support by creating simplefb devices wherever possible. More background can be found at http://lwn.net/Articles/558104/" * 'x86-fb-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: fbdev: fbcon: select VT_HW_CONSOLE_BINDING fbdev: efifb: bind to efi-framebuffer fbdev: vesafb: bind to platform-framebuffer device fbdev: simplefb: add common x86 RGB formats x86: sysfb: move EFI quirks from efifb to sysfb x86: provide platform-devices for boot-framebuffers fbdev: simplefb: mark as fw and allocate apertures fbdev: simplefb: add init through platform_data
