From d71bd34d78bb78b9e6f8a0be3952d5fa470a260a Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Mon, 15 Jan 2018 20:52:07 -0600 Subject: tracing: Make tracing_set_clock() non-static Allow tracing code outside of trace.c to access tracing_set_clock(). Some applications may require a particular clock in order to function properly, such as latency calculations. Also, add an accessor returning the current clock string.
