Nope.  DRM_NAME is #defined only once.

include/drm/drm.h:#define DRM_NAME	"drm"	

The only real reason to do this is the "*ERROR*"
used in:

It'd be more or less similar to use:

#define DRM_ERROR(fmt, ...)	\
	pr_err("%s: " fmt, __func__, ##__VA_ARGS__)

or just convert DRM_ERROR to pr_err and DRM_INFO to pr_info.
