[PATCH 07/15] v4l: vsp1: Move DRM atomic commit pipeline setup to separate function
Laurent Pinchart

Mon Feb 26 21:45:08 UTC 2018
The DRM pipeline setup code used at atomic commit time is similar to the
setup code used when enabling the pipeline. Move it to a separate
function in order to share it.
