I think the uvc_trace_cont mechanism should require a flag and not assume UVC_TRACE_PROBE so it's possible, even though currently unused, for other uvc_trace calls to be continued. $ git grep -Poh '\buvc_trace\(\w+' drivers/media | sort | uniq -c 1 uvc_trace(flag 6 uvc_trace(UVC_TRACE_CALLS 1 uvc_trace(UVC_TRACE_CAPTURE 2 uvc_trace(UVC_TRACE_CLOCK 15 uvc_trace(UVC_TRACE_CONTROL 42 uvc_trace(UVC_TRACE_DESCR 6 uvc_trace(UVC_TRACE_FORMAT 12 uvc_trace(UVC_TRACE_FRAME 7 uvc_trace(UVC_TRACE_PROBE 1 uvc_trace(UVC_TRACE_STATS 6 uvc_trace(UVC_TRACE_STATUS 4 uvc_trace(UVC_TRACE_SUSPEND 6 uvc_trace(UVC_TRACE_VIDEO
