+Subject: [PATCH] brcmfmac: remove restriction from .sched_scan_start()
+ callback
+
+In the .sched_scan_start() callback a condition was checked whether a
+normal scan was ongoing. However, there is no need for this check as
+it is ok to start the scheduled scan irrespective whether or not a
+normal scan is ongoing.
