Subject: [RFC PATCH 02/17] zd1211rw: cancel process_intr work on zd_chip_disable_int()
Date: Wed, 05 Jan 2011 01:48:03 +0200 [thread overview]
Message-ID: <20110104234802.25309.55896.stgit@fate.lan> (raw)
In-Reply-To: <20110104234745.25309.72030.stgit@fate.lan>
OOPS if worker is running and disconnect() is called (triggered
by unpluging device). Much harder to trigger at this stage but
later when we have AP beacon work in process_intr it happens very
easy.
