Subject: [PATCH v8 30/35] drm+drivers: adapt to use DYNDBG_CLASSMAP_{DEFINE,USE}
Date: Mon, 29 Apr 2024 13:39:16 -0600

Follow dynamic_debug API change from DECLARE_DYNDBG_CLASSMAP to
DYNDBG_CLASSMAP_{DEFINE,USE}.

Prior to this, we used DECLARE_DYNDBG_CLASSMAP, which was preserved to
decouple DRM conversion.  I'm unsure of the full functionality
in-between, a round of lkp-testing will help.

Fixes: f158936b60a7 ("drm: POC drm on dyndbg - use in core, 2 helpers, 3 drivers.")
