Oh these look like a good plan, one of our contributors has an inline
fetish and it got cut-n-pasted into a few places particular in radeon.
But we won't be turning DRM debugging off, its what we use to debug things
in the field, I did get a patch recently to reduce some of its overhead
5ad3d8831f0c97257460c11ddcc1cc0466c762d4 in my drm-next branch,
drm: Create and use drm_err from Joe Perches.
Dave.
