Hi Linus,
This just another macro removal, the counter macros are gone...

drm: drop __HAVE_COUNTER macros
This removes all the __HAVE_COUNTER macro and replaces them with
the driver setting the values in its register_fns.

While I definitly approve this patch is there a specific reason for this
array instead of individual members like
lock_cnt, open_cnt, close_cnt, etc..?
also the optional counters seem to be largely overlapping, why not always
all four thta exist and if some drivers don't want to update them they'd
just not update them
Well this was only a direct macro removal, I'm contemplating removing the
counters as to be honest I'm not sure any drm developer as actually used
them since day one .. (and maybe not even then)... but I'll leave that for
another time, as there might be a wierd use of them somewhere...
Once I drop the ioctl macro, I'll probably start going back to see what
stuff is probably not of any use anymore.. (counters are fairly high on
that list..)..

Sure, and I really like the patch. But seeing code posted is the best
place for further suggestions in that area.

Sounds like a good idea. Especially as dev->counts are atomic_ts that are
rather expensive.
