Re: [PATCH RFC] usb: atm: cxacru: fix NULL pointer dereference on uninitialized atm_dev

The cxacru_poll_status() hunk guards an unreachable state:
cxacru_atm_start() only fails on the MAC read, which is before polling
starts, so usbatm_atm_init() never reaches its atm_dev = NULL path with
poll_work pending, and cxacru_unbind() already cancels the work via
cancel_delayed_work_sync().
