Subject: [PATCH] cfg80211: fix unregistration
Date: Mon, 13 Jul 2009 13:24:44 +0200 [thread overview]
Message-ID: <1247484284.4166.3.camel@johannes.local> (raw)
The work that we cancel there requires the cfg80211_mutex,
so we can't cancel it under the mutex, which is fine, we
can just move it to after the locked section.
