No, that isn't is. ctrl_handling is set in the open (it's a m2m device, so the controls are per-filehandle), and V4L2_FL_USES_V4L2_FH is set implicitly whenever you call v4l2_fh_init. But know I remember, it was a regression in v4l2-ioctl.c that's fixed here: http://patchwork.linuxtv.org/patch/13377/ Regards, Hans -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
