Merge tag 'fbdev-reorder-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux

Pull fbdev renaming patches from Tomi Valkeinen:
 "Reorder drivers/video/ directory so that all fbdev drivers are now
  located in drivers/video/fbdev/ and the fbdev framework core files are
  located in drivers/video/fbdev/core/

  The drivers/video/Kconfig is modified so that the DRM and the fbdev
  menu options are in separate submenus, instead of both being mixed in
  the same 'Graphics support' menu level"

* tag 'fbdev-reorder-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux:
  video: Kconfig: move drm and fb into separate menus
  fbdev: move fbdev core files to separate directory
  video: move fbdev to drivers/video/fbdev
