net: qrtr: correct types of trace event parameters
[ Upstream commit 054fbf7ff8143d35ca7d3bb5414bb44ee1574194 ]
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
