Subject: [PATCH 2/2] can: usb_8dev: fix urb leak on failure path in usb_8dev_start()
Date: Fri, 19 Jul 2013 15:17:49 +0200	[thread overview]
Message-ID: <1374239869-27085-3-git-send-email-mkl@pengutronix.de> (raw)
In-Reply-To: <1374239869-27085-1-git-send-email-mkl@pengutronix.de>

From: Alexey Khoroshilov <khoroshilov@ispras.ru>

If usb_8dev_start() fails to submit urb,
it unanchors the urb but forgets to free it.

Found by Linux Driver Verification project (linuxtesting.org).
