From 4f871a9f0f6fbb8ab023cca1f0099bf152a5d618 Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Wed, 2 Aug 2017 10:21:56 -0600 Subject: [PATCH] coresight: etb10: Remove useless conversion to LE Internal CoreSight components are rendering trace data in little-endian format. As such there is no need to convert the data once more, hence removing the extra step.
