Subject: [PATCH v2 0/2] drm/msm/dpu: two fixes targeting 6.11

Leonard Lausen reported an issue with suspend/resume of the sc7180
devices. Fix the WB atomic check, which caused the issue. Also make sure
that DPU debugging logs are always directed to the drm_debug / DRIVER so
that usual drm.debug masks work in an expected way.

      drm/msm/dpu1: don't choke on disabling the writeback connector
      drm/msm/dpu: don't play tricks with debug macros
