Merge branch 'console-fixes' into drm-next
(not the fbcon maintainer pull 2) fix bug in vgacon on bootup and fbcon losing fonts on startup. * console-fixes: (50 commits) fbcon: don't lose the console font across generic->chip driver switch vgacon/vt: clear buffer attributes when we load a 512 character font (v2)
