Also noticing just now that this whole patch makes sblk unused:

drivers/gpu/drm/msm/disp/dpu1/dpu_hw_sspp.c: In function '_dpu_hw_sspp_init_debugfs':
drivers/gpu/drm/msm/disp/dpu1/dpu_hw_sspp.c:620:41: warning: unused variable 'sblk' [-Wunused-variable]
  620 |         const struct dpu_sspp_sub_blks *sblk = cfg->sblk;
      |                                         ^~~~
