Xu Yang 256c3e6192 usb: roles: don't get/set_role() when usb_role_switch is unregistered ... commit b787a3e781759026a6212736ef8e52cf83d1821a upstream. There is a possibility that usb_role_switch device is unregistered before the user put usb_role_switch. In this case, the user may still want to get/set_role() since the user can't sense the changes of usb_role_switch. This will add a flag to show if usb_role_switch is already registered and avoid unwanted behaviors.
