Subject: [PATCH 35/38] tools lib traceevent: Use pevent_print_func_field in hrtimer_start handler

From: Jiri Olsa <jolsa@...hat.com>

The pevent_print_func_field function encompasses all the functionality
used in the hrtimer_start handler. Change the handler to use this
function.

This also unifies the function field output with the
hrtimer_expire_entry handler.
