[RFC PATCH 0/9] drm: add more new-style logging functions

[Sam Ravnborg]

Jani Nikula introduced the new nice drm_* logging functions.
I looked at updating drm/panel/* to use these,
but was quickly faced with the fact that in
many cases there was a device * but no drm_device *.
And in some cases not even a device *.

So we would end up with a mixture of different type
of logging making it confusing when to use what.
Somethign that alos IMO hurts the readability of the code.

Likewise for review feedback where we cannot simply tell
people to use new style logging but have to explain when
to use what. This will be confusing.

This patchset starts by introducing brief documentation
of the new style logging functions - something I have missed.
And then it introduces new style logging for the remaining
types of logging.

    drm_dev_*	- when a device * is avialable
    drm_pr_*	- when no identification is available

The last patch change the now legacy logging functions to
use the new style logging functions and in the process
delete a few now unused functions.
No conversion of actual users included - that will come
later when we have agreed on namign etc.

The patchset is not yet tested - but it builds.
This is an early drop of the patches to trigger
feedback on naming, get early feedback on documentation,
and any other good comments.
