Merge tag 'for-5.19/fbdev-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev

Pull fbdev fixes from Helge Deller:
 "Two bug fixes for the pxa3xx and intelfb drivers:

   - pxa3xx-gcu: Fix integer overflow in pxa3xx_gcu_write

   - intelfb: Initialize value of stolen size

  The other changes are small cleanups, simplifications and
  documentation updates to the cirrusfb, skeletonfb, omapfb,
  intelfb, au1100fb and simplefb drivers"
