Subject[PATCH v2 01/17] coresight: trbe: Fix incorrect access of the sink specific data
Date
The TRBE driver wrongly treats the aux private data as the TRBE driver
specific buffer for a given perf handle, while it is the ETM PMU's
event specific data. Fix this by correcting the instance to use
appropriate helper.
