Subject: tracing: use generic __stringify
X-Git-Tag: firefly_0821_release~13991^2~249^2~4
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9cc26a261d43e5898287a1f5808132f8f05ceb1c;p=firefly-linux-kernel-4.4.55.git

tracing: use generic __stringify

Impact: clean up

This removes the custom made STR(x) macros in the tracer and uses
the generic __stringify macro instead.
