Subject: [PATCH] usb: gadget: configs: plug memory leak
Date: Tue, 28 Feb 2017 10:55:30 +0000 [thread overview]
Message-ID: <20170228105530.5485-1-john@metanate.com> (raw)
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.
