commit1366cd228bupstream. If ports are defined in the tcpc main node, fwnode_usb_role_switch_get() returns an error, meaning usb_role_switch_get() (which would succeed) never gets a chance to run as port->role_sw isn't NULL, causing a regression on devices where this is the case. Fix this by turning the NULL check into IS_ERR_OR_NULL(), so usb_role_switch_get() can actually run and the device get properly probed.
