Thanks for the reviews. I've pushed the patches to a new topic branch
drm-intel/topic/drm-mipi-dsi-dsc-updates per feedback from Sean and
Daniel. I'll be needing these dependencies in i915 sooner than a
roundtrip through drm-misc->drm-next->drm-intel would be convenient.
I'll send a pull request to drm-misc soonish, and will also pull to
drm-intel after the merge to drm-misc.
Please holler if you have any issues with this.
BR,
Jani.
