[PATCH 0/7] Add DP MST AUX devices

[Lyude Paul]

Hi, could we (and for future versions of this series and others) get a respin
of this that's actually rebased against drm-tip? That is the defacto standard
branch to do development on, and otherwise anyone trying to test these patches
has to resolve merge conflicts (along with maintainers). The branch this
appears to be based off of doesn't even have the new kref scheme for branch
devices and ports.
