However, the\nparent device of usb_role_switch may be removed before the user put the\nusb_role_switch. If so, then, NULL pointer issue will be met when the user\nput the parent module's reference.\n\nThis will save the module pointer in structure of usb_role_switch. Then,\nwe don't need to find module by iterating long relations."
