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.
