   4 Subject: [PATCH] brcmfmac: remove restriction from .sched_scan_start()
   5  callback
   6
   7 In the .sched_scan_start() callback a condition was checked whether a
   8 normal scan was ongoing. However, there is no need for this check as
   9 it is ok to start the scheduled scan irrespective whether or not a
  10 normal scan is ongoing.
