Use a single implementation for all. v2: use static inline (Alex Xie) Reviewed-by: Alex Xie Suggested-by: Andres Rodriguez Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h index e02044086445..2d846ef1c033 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h @@ -30,4 +30,17 @@ void amdgpu_gfx_scratch_free(struct amdgpu_device *adev, uint32_t reg);
