drm: modes: Revert cc344980c767 "replace simple_strtoul by kstrtouint"topic/drm-misc-2015-12-14
My latest commit introduce some case where a valid mode, could be rejected. simple_strtox functions stop at first non-digit character, but kstrtox not. So args like "video=HDMI-A-1:720x480-16@60" will be reject when checking 16@. Discussions about this change comes to the conclusion that the best solution is to revert my commit cc344980c76748e57c9c03100c2a14d36ab00334.
