media: v4l: fwnode: Use V4L2 fwnode endpoint media bus type if set

Browse source

Use the given media bus type set by the caller. If none is given (i.e. the
mbus type is V4L2_MBUS_UNKNOWN, or 0), fall back to the old behaviour.
This is to obtain the information from the DT or try to guess the bus
type.

-ENXIO is returned if the caller sets the bus type but that does not match
with what's in DT. Also return -ENXIO if bus type detection failed to
separate this from the rest of the errors.
