[PATCH 0/2] v4l-utils: media-ctl: Print media graph completes if available

[Niklas Söderlund]

Hi,

This series adds the option to print the media graphs completes if its 
available. This series is intended as a demo of the use-case for the 
patches posted to the media mailing list in [1].

The series is based on-top of latest v4l-utils master branch. Patch 1/2
is not meant for consumption but to ease testing of patch 2/2. Patch 1/2
should be replaced with a proper header after [1] is picked up up in 
Linux.
