9403f9a42c drm/msm/dpu: merge base_off with blk_off in struct dpu_hw_blk_reg_map 
There is little point in keeping a separate MDP address and block offset
in this struct. Merge them to form a new blk_addr field used for all
register access.

1e5df24b99 drm/msm/dpu: drop length from struct dpu_hw_blk_reg_map 
We (nearly) do not use the length field from struct dpu_hw_blk_reg_map,
so we can drop it safely.

129ae533fa drm/msm/dpu: remove hwversion field from data structures 
The driver should not depend on hw revision for detecting features.
Instead it should use features from the hw catalog. Drop the hwversion
field from struct dpu_mdss_cfg and struct dpu_hw_blk_reg_map.

170b22234d drm/msm/dpu: invalid parameter check in dpu_setup_dspp_pcc 
The function performs a check on the "ctx" input parameter, however, it
is used before the check.

Initialize the "base" variable after the sanity check to avoid a
possible NULL pointer dereference.

88b0f5a56d drm/msm/dpu: remove unused dpu_hw_blk features 
Remove all unused dpu_hw_blk features and functions:
- dpu_hw_blk_get()/_put() and respective refcounting,
- global list of all dpu_hw_blk instances,
- dpu_hw_blk_ops and empty implementation inside each hw_blk subdriver.

This leaves dpu_hw_blk as a placeholder with just type and index.
