[PATCH v2 39/59] drm-dyndbg: DRM_CLASSMAP_USE in amdgpu driver

[Louis Chauvet]

Le 20/03/2025 à 19:52, Jim Cromie a écrit :
> Following the dyndbg-api-fix, replace DECLARE_DYNDBG_CLASSMAP with
> DRM_CLASSMAP_USE.  This refs the defined & exported classmap, rather
> than re-declaring it redundantly, and error-prone-ly.
> 
> This resolves the appearance of "class:_UNKNOWN_" in the control file
> for the driver's drm_dbg()s.
> 
> Fixes: f158936b60a7 ("drm: POC drm on dyndbg - use in core, 2 helpers, 3 drivers.")
