Re: [PATCH v2] 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.

Changes: v2: Fixed error in coccinelle script and diff, i.e. removed the underscore. drv_dbg_ -> drm_dbg

Applied to drm-misc-next, thanks for your patch. Will probably go to 5.10 because drm is already in feature freeze. -Daniel
