media: v4l2-subdev: add v4l2_subdev_get_fwnode_pad_1_to_1

Browse source

Add a convenience function that can be used as the .get_fwnode_pad
operation for subdevices that map port numbers and pad indexes 1:1.
The function verifies the endpoint is owned by the subdevice, and if
so returns the endpoint port number.
