After it calls pm_runtime_enable(), it only have a regular path whichs return 0 and indicates the probe is successful. It doesn't have error handling path. regmap_read() function returns a negative errno in error cases, but it is used to get Microchip XISC version. I am not sure if failure means the probe fails. > > unregister_v4l2_device: > > v4l2_device_unregister(&isc->v4l2_dev); > > > > -- > > 2.17.1 > > >
