Subject: fbcon: delay screen update when setting the mode of all consoles
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
If the current framebuffer console is rotated (rotate != 0), doing an
"fbset -a" will corrupt the current console. Fix by updating the current
console only after all non-visible consoles have been updated.
