Subject: [PATCH 0/3] drm/msm/dpu: Drop useless for-loop HW block lookup

Doing a for loop in every DPU HW block driver init to find a catalog
entry matching the given ID is rather useless if the init function
called by RM already has that catalog entry pointer, and uses exactly
its ID to drive this init and for loop.  Remove all that machinery to
drop quite some lines of unnecessarily-complicated code, and the
fallibility that comes with it, by simply giving _init() the catalog
entry pointers straight away.

Also clean up some unused struct members, and assign a log_mask for WB.

Marijn Suijten (3):
      drm/msm/dpu: Drop unused members from HW structs
      drm/msm/dpu: Assign missing writeback log_mask
      drm/msm/dpu: Pass catalog pointers directly from RM instead of IDs
