#1207846 — [PATCH 4.1 26/84] usb: udc: core: add device_del() call to error pathway

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

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

From: Alan Stern <stern@rowland.harvard.edu>

commit c93e64e91248becd0edb8f01723dff9da890e2ab upstream.

This patch fixes a bug in the error pathway of
usb_add_gadget_udc_release() in udc-core.c.  If the udc registration
fails, the gadget registration is not fully undone; there's a
put_device(&gadget->dev) call but no device_del().
