Subject: [PATCH 2/2] pda_power: Unregister USB notifier in pda_power_remove()
Date: Sun, 30 Mar 2014 15:34:15 +0200 [thread overview]
Message-ID: <1396186455-3276-3-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <1396186455-3276-1-git-send-email-minipli@googlemail.com>
If we've registered a notifier in pda_power_probe() we must deregister
it in pda_power_remove() to not let it work on stale data like, e.g.,
the charger timer.
