Hello,

This patch series improves the KMS sink in cam to scale the frame buffer
to full screen when supported by the hardware, and to center the image
instead of aligning it to the top-left corner otherwise.

The series has been tested on a RockPi 4 board.

Please see individual patches for details.

Laurent Pinchart (3):
  cam: drm: Add support for test-only commits
  cam: kms_sink: Make lifetime management of DRM request safer
  cam: kms_sink: Scale the frame buffer to full screen if supported
