-Subject: [PATCH] brcmfmac: Fix race condition in msgbuf ioctl processing.
-
-Msgbuf is using a wait_event_timeout to wait for the response on
-an ioctl. The wakeup routine uses waitqueue_active to see if
-wait_event_timeout has been called. There is a chance that the
-response arrives before wait_event_timeout is called, this
-will result in situation that wait_event_timeout never gets
-woken again and assumed result will be a timeout. This patch
-removes that errornous situation by always setting the
-ctl_completed var before checking for queue active.
