This reverts commit1366cd228b. The fwnode_usb_role_switch_get() returns NULL only if no connection is found, returns ERR_PTR(-EPROBE_DEFER) if connection is found but deferred probe is needed, or a valid pointer of usb_role_switch. When switching from a NULL check to IS_ERR_OR_NULL(), usb_role_switch_get() returns NULL and overwrites the ERR_PTR(-EPROBE_DEFER) returned by fwnode_usb_role_switch_get(). This causes the deferred probe indication to be lost, preventing the USB role switch from ever being retrieved.
