When DRM_USE_DYNAMIC_DEBUG=3Dy, DYNDBG_CLASSMAP_DEFINE() maps DRM_UT_* onto BITs in drm.debug. This still uses enum drm_debug_category, but it is somewhat indirect, with the ordered set of DRM_UT_* enum-vals. This requires that the macro args: DRM_UT_* list must be kept in sync and in order. Fixes: f158936b60a7 ("drm: POC drm on dyndbg - use in core, 2 helpers, 3 dr= ivers.")
