[PATCH v2 00/20] drm: Use new DRM printk funcs (like drm_dbg_*()) in DP helpers

[Lyude Paul]

Since it's been asked quite a few times on some of the various DP
related patch series I've submitted to use the new DRM printk helpers,
and it technically wasn't really trivial to do this before due to the
lack of a consistent way to find a drm_device for an AUX channel, this
patch series aims to address this. In this series we:

* Clean-up potentially erroneous usages of drm_dp_aux_init() and
  drm_dp_aux_register() so that actual AUX registration doesn't happen
  until we have an associated DRM device
* Clean-up any obvious errors in drivers we find along the way
* Add a backpointer to the respective drm_device for an AUX channel in
  drm_dp_aux.drm_dev, and hook it up in every driver with an AUX channel
  across the tree
* Add a new ratelimited print helper we'll need for converting the DP
  helpers over to using the new DRM printk helpers
* Fix any inconsistencies with logging in drm_dp_helper.c so we always
  have the aux channel name printed
* Prepare the various DP helpers so they can find the correct drm_device
  to use for logging
* And finally, convert all of the DP helpers over to using drm_dbg_*()
  and drm_err().

Series-wide changes in v2:
* Address most checkpatch issues ('most' as in all except for one line
  going two chars over 100 in "drm/dp_mst: Pass drm_dp_mst_topology_mgr
  to drm_dp_get_vc_payload_bw()" as this was the style in use
  previously, and 2 chars over the limit looks nicer then trying to
  line-wrap this
* Don't rewrap comments
