Swapping the order between v4l2 subdevice registration and checking chip id in
b7a417628abf ("media: ov2680: don't register the v4l2 subdevice before checking chip ID")
makes the mode restore to use the sensor controls before they are set, so move
the mode restore call to s_power after the handler setup for controls is done.
This remove also the need for the error code path in power on function.
