From f72b3bc46dab124c25d84575d3addab8ef7c68cd Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Wed, 17 Feb 2016 17:51:46 -0700 Subject: coresight: add API to get sink from path Add an API allowing external code to quickly get a handle on the sink within a path. The sink is always last, but adding an API allows to keep the path's node structure private and remove redundant checks.
