Re: [PATCH] Remove unused function drm_agp_bind_pages

[Sam Ravnborg]

Hi Maya.

Nice catch - good to remove unused cruft.

Please prefix the subject with something like "drm/agp: ".
Check "git log" on the same file to pick up the usual way to identify
agp specific changes.

With this fixed:
Reviewed-by: Sam Ravnborg <sam@ravnborg.org>

You could also consider to add a few words in the body of the changelog
how the unused function was identified.
