fbdev: propagate result of fb_videomode_from_videomode()
fb_videomode_from_videomode() may fail, but of_get_fb_videomode() silently covers this fact. Instead, trow the error code to the caller. Signed-off-by: Vladimir Murzin <vladimir.murzin@arm.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
