  fbcon: Use fbcon_info_from_console() in fbcon_modechange_possible() (2022-07-07 10:52:35 +0200)

----------------------------------------------------------------
fbdev fixes and updates for kernel v5.19-rc6:

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.
