-Subject: [PATCH] brcmfmac: fix handling ssids in .sched_scan_start() callback
-
-The ssids list in the scheduled scan request were not properly taken
-into account when configuring in firmware. The hidden bit was set for
-any ssid resulting in active scanning for all. Only set it for ssids
-that are in the ssids list.
