[PATCH] USB: UDC core: add device_del() call to error pathway

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().
