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"
