Subject[PATCH 2/6] tracing: have TRACE_EVENT macro use __flags to not shadow parameter
From: Steven Rostedt <srostedt@redhat.com>

The generated functions of TRACE_EVENT uses "flags" in one of the
sub macros which shadows a parameter in the outside macro.

Simple fix is to make the submacro use __flags instead.

Discovered by sparse.
