Merge tag 'fbdev-for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev

Pull fbdev updates from Helge Deller:
 "Three fbdev drivers (~8500 lines of code) removed. The Carillo Ranch
  fbdev driver is for an Intel product which was never shipped, and for
  the intelfb and the amba-clcd drivers the drm drivers can be used
  instead.

  The other code changes are minor: some fb_deferred_io flushing fixes,
  imxfb margin fixes and stifb cleanups.

  Summary:
   - Remove intelfb fbdev driver (Thomas Zimmermann)
   - Remove amba-clcd fbdev driver (Linus Walleij)
   - Remove vmlfb Carillo Ranch fbdev driver (Matthew Wilcox)
   - fb_deferred_io flushing fixes (Nam Cao)
   - imxfb code fixes and cleanups (Dario Binacchi)
   - stifb primary screen detection cleanups (Thomas Zimmermann)"
