Hi,

[it seems your Reply-To mail header is set strangely as

There exists DRM_DEV_ERROR, DRM_DEV_INFO and DRM_DEV_DEBUG to
handle actual devices. Interestingly there is no DRM_DEV_WARN though.

So depending on what Sean suggest another option would be to add the
missing DRM_DEV_WARN and then use it to replace the dev_warn.
