The arguments passed to the trace events are of type unsigned int, however the signature of the events used __le32 parameters. I may be missing the point here, but sparse flagged this and it does seem incorrect to me. net/qrtr/ns.c: note: in included file (through include/trace/trace_events.h, include/trace/define_trace.h, include/trace/events/qrtr.h): ./include/trace/events/qrtr.h:11:1: warning: cast to restricted __le32 ./include/trace/events/qrtr.h:11:1: warning: restricted __le32 degrades to integer ./include/trace/events/qrtr.h:11:1: warning: restricted __le32 degrades to integer ...
