[PATCH] ath10k: add device/driver strings to tracepoints
Michal Kazior

Thu Aug 28 06:05:35 PDT 2014
This makes it easier to log and debug via tracing
with more than 1 ath10k device on a system.

Not sure if pulling core.h in trace.h and using ar
pointer is the best approach here. Alternative is
to not pull core.h and pass ar->dev directly to
trace functions. Thoughts?
