Merge tag 'for-5.19/fbdev-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev
Pull fbdev fixes from Helge Deller:
- fbcon now prevents switching to screen resolutions which are smaller
than the font size, and prevents enabling a font which is bigger than
the current screen resolution. This fixes vmalloc-out-of-bounds
accesses found by KASAN.
- Guiling Deng fixed a bug where the centered fbdev logo wasn't
displayed correctly if the screen size matched the logo size.
- Hsin-Yi Wang provided a patch to include errno.h to fix build when
CONFIG_OF isn't enabled.
