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:
* (NEW!) Move i2c adapter setup into drm_dp_aux_init() and add
drm_dp_aux_fini()
* 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().
