[libcamera-devel] [PATCH 3/3] libcamera: pipeline: Register device numbers with camera

[Kieran Bingham]

Register the identified device numbers with each camera as the Devices
property.

This facilitates camera daemons or other systems to identify which
devices are being managed by libcamera, and can prevent duplication of
camera resources.
