[PATCH 4.13 11/27] brcmfmac: feature check for multi-scheduled scan fails on bcm4345 devices

From: Greg Kroah-Hartman
Date: Tue Sep 12 2017 - 13:08:11 EST


4.13-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ian W MORRISON <ianwmorrison@xxxxxxxxx>

commit f957dd3c8db2781c8a334b166800788feb618625 upstream.

The firmware feature check introduced for multi-scheduled scan is also
failing for bcm4345 devices resulting in a firmware crash.
The reason for this crash has not yet been root cause so this patch avoids
the feature check for those device as a short-term fix.
