[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: John Keeping <j...@metanate.com>


[ Upstream commit 38355b2a44776c25b0f2ad466e8c51bb805b3032 ]

When binding a gadget to a device, "name" is stored in gi->udc_name, but
this does not happen when unregistering and the string is leaked.
