Merge tag 'fbdev-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev
Pull fbdev updates from Helge Deller:
"The most relevant change are the patches from Dmitry Torokhov to
switch omapfb to the gpiod API.
The other patches are small and fix e.g. UML build issues, improve the
error paths and cleanup code"
