Subject: mac80211: Cancel the dynamic ps timer in ioctl_siwpower.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b8abde45d7d6ab9e8ceced9b5990eeb1149d0b97;p=linux-beck.git

mac80211: Cancel the dynamic ps timer in ioctl_siwpower.

If the dynamic power save timer has been started before the power save
is disabled using iwconfig, we fail to cancel the timer. Hence cancel it
while disabling power save.
