Subject: [PATCH v3 5/7] tracing: Move hist trigger key printing into a separate function
Date: Thu,  9 Aug 2018 09:34:15 -0500
Message-ID: <456e83f562bea689ce01305628abeee2e46f6e6a.1533753152.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1533753152.git.tom.zanussi@linux.intel.com>

From: Tom Zanussi <tom.zanussi@linux.intel.com>

Future patches will want to print a histogram key outside a histogram
- add and use hist_trigger_print_key() for that purpose.
