[libcamera-devel] [PATCH 3/3] libcamera: request: Use external CameraControlValidator

[Kieran Bingham]

Each Request is currently creating its own CameraControlValidator
using the Camera instance at construction.

Now that the Camera exposes its own CameraControlValidator on its
private interface, use that one on all Requests.
