Subject: [PATCH 2/3] [media] coda: Unregister v4l2 upon alloc_workqueue() error
Date: Sat, 4 Oct 2014 16:40:51 -0300 [thread overview]
Message-ID: <1412451652-27220-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1412451652-27220-1-git-send-email-festevam@gmail.com>
From: Fabio Estevam <fabio.estevam@freescale.com>
If alloc_workqueue() fails, we should go to the 'err_v4l2_register' label, which
will unregister the v4l2 device.
