Subject: mac80211: Cancel the power save timer in ieee80211_stop.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7cbf0ba5193d1f3bb3caaa06668e22bc86776e41;p=linux-beck.git

mac80211: Cancel the power save timer in ieee80211_stop.

Since the station info is flushed before calling set_disassoc
in ieee80211_stop, the power save timer is never cancelled
when the driver is unloaded. Hence the timer cancellation has
to be done in ieee80211_stop itself.
