[PATCH] fbcon: Code cleanups
- replace kmalloc with kzalloc - remove repeated define (FONTCHHCNT) - remove unneeded local variable (redraw) in ypan_{up|down}_redraw - add and delete cursor timer in fbcon_switch() if old_info != info Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
