ath10_pci: WARN(() on resume from S3

From: Gabriel C
Date: Thu Dec 27 2018 - 05:17:20 EST


Hello ,

on a QCA9377 card I hit WARN() on each resume from S3.

This is on kernel 4.19.X and now on 4.20.0 too.
On kernel 4.19.x I see just the first WARN() while on
4.20.0 I see now two.

Also I see Unknown eventid: xxx and on 4.20.0
a unsupported HTC service id: xxx message(s).
