The first patch fixes a bug in querystd: if there is no signal, then querystd should return V4L2_STD_UNKNOWN. There are more drivers that return the wrong value here, I have a patch series pending to fix that and also to improve the spec. The second does a code cleanup that improves readability, but it doesn't change the logic. The third patch is based on a patch from Mauro and a patch from Leo: https://patchwork.linuxtv.org/patch/18573/ https://linuxtv.org/patch/18399/ This improves the error handling in case usb_control_msg() returns an error. Changes since v1: - Also return the low-level usb_control_msg error in the vidioc_g_fmt_vid_cap case.
