+Subject: [PATCH] brcmfmac: fix watchdog timer regression
+
+The watchdog timer is used to put the device in a low-power mode when
+it is idle for some time. This timer is stopped during that mode and
+should be restarted upon activity. This has been broken by commit
+d4150fced0365 ("brcmfmac: Simplify watchdog sleep."). This patch
+restores the behaviour as it was before that commit.
