Message-Id: <1358783440-11459-4-git-send-email-bjorn@mork.no> Date: Mon, 21 Jan 2013 16:50:40 +0100 From: Bjørn Mork <bjorn@...k.no> To: netdev@...r.kernel.org Cc: linux-usb@...r.kernel.org, Greg Suarez <gsuarez@...thmicro.com>, Alexey Orishko <alexey.orishko@...ricsson.com>, Oliver Neukum <oneukum@...e.de>, Bjørn Mork <bjorn@...k.no> Subject: [PATCH net 3/3] net: cdc_ncm: fix error path for single interface probing commit bbc8d92 (net: cdc_ncm: add Huawei devices) implemented support for devices with a single combined control and data interface. Fix up the error path so that we do not double release such interfaces in case of probing failures.
