Subject: [PATCH] drm: core: Convert device logging to drm_* functions.

Convert device logging with dev_* functions into drm_* functions.

The patch has been generated with the coccinelle script below.
The script focuses on instances of dev_* functions where the drm device
context is clearly visible in its arguments.

This is an error here.
drm_dbg_ isn't any function.

Resending this patch.

Thanks,

Looks good, coccinelle is a reliable way for such mass conversion.

When converting to new style logging then all logging should be
converted in a file. Maybe, if too much, split in two patches.
But for all three files there are logging remaining to be converted
so we would end up in several patch-sets before done.
Please try to extend the scripting to also cover DRM_ => drm_ logging.
You may need some manual adjustments to cover it all.
