Dear Linus,

please pull a few fbdev fixes for kernel v7.3-rc3:

Two patches for VT core code and fbcon prevent potential out-of-bounds
reads on font or screen size changes, one fix limits the Superblitter in
atafb to supported modes only, and some minor fixes for vfb, ssd1307fb
and omapfb.

Thanks!
Helge
