Subject: [PATCH v8-RESEND 28/33] drm+drivers: adapt to use DYNDBG_CLASSMAP_{DEFINE,USE}
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.")
