For drivers, add the decl just above the module's PARAMs, since it identifies the "inherited" drm.debug param. Note: with CONFIG_DRM_USE_DYNAMIC_DEBUG=y, a module not also declaring DRM_CLASSMAP_USE will have its class'd prdbgs stuck in the initial (disabled, but for DEBUG) state. The stuck sites are evident in /proc/dynamic_debug/control as: class unknown, _id:N # control's last column rather than a proper "enumeration": class:DRM_UT_CORE This set of updates was found by choosing M for all DRM-config items I found (not allmodconfig), building & modprobing them, and grepping "class unknown," control. There may yet be others.
