Yes, week ago I saw omap_udc crashing on both probe failure and
module removal and sent some fixes for the most obvious failures (see
https://marc.info/?l=linux-usb&m=154258778316932&w=2).
Is there any good driver that uses usb_add_gadget_udc_release() correctly?
Looking at fsl_qe_udc.c and fsl_udc_core.c they should also crash if
usb_add_gadget_udc_release() fails.
