There is just 1 user of DPU_DEBUG_DRIVER and 29 users of DPU_DEBUG. So we might instead replace them with DRM_DEBUG_* calls and drop the DPU_DEBUG/DPU_DEBUG_DRIVER altogether. DPU_ERROR is used in ~190 places, so it will be more intrusive, but still doable. > Changes in v5: > -Added to the set > Changes in v6: > -None > --- > drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 20 ++++---------------- > 1 file changed, 4 insertions(+), 16 deletions(-) > > diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h > index 323a6bce9e64..c33164d3944a 100644 > --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h > +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h > @@ -31,27 +31,15 @@ > * DPU_DEBUG - macro for kms/plane/crtc/encoder/connector logs > * @fmt: Pointer to format string > */ > -#define DPU_DEBUG(fmt, ...) \ > - do { \ > - if (drm_debug_enabled(DRM_UT_KMS)) \ > - DRM_DEBUG(fmt, ##__VA_ARGS__); \ > - else \ > - pr_debug(fmt, ##__VA_ARGS__); \ > - } while (0) > +#define DPU_DEBUG(fmt, ...)
