video: fbdev: uvesafb: Remove impossible code path in uvesafb_init_info
Because uvesafb_vbe_init will fail when get zero avaiable modes, and we have checked the return value of uvesafb_vbe_init_mode, so it is impossible to pass NULL as mode into uvesafb_init_info. [ This patch fix warning report by fengguang.wu@intel.com "drivers/video/fbdev/uvesafb.c:1509 uvesafb_init_info() error: we previously assumed 'mode' could be null" ] Signed-off-by: Wang YanQing <udknight@gmail.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
