4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ashok Raj Nagarajan <arnagara@xxxxxxxxxxxxxxxx>
commit 53a5c9bc53ce51f65699a43c67ab167436d28083 upstream.
Currently, we are providing wrong payload data of pktlog to trace points.
Data we receive from FW through copy engine 8 contains pktlog data alone.
We don't need to parse anything in driver before handing it to trace
points.
Fixes: afb0bf7f530b ("ath10k: add support for pktlog in QCA99X0")
