So the "len" of the blocks having sub-blocks will be ignored in favor of the len of the sub-blocks. If we remove this without adding that support first, its a loss of debug functionality. Can we retain these blocks and remove dpu_debugfs_create_regset32 in a different way?

[PATCH 1/2] drm/msm/dpu: drop SSPP register dumpers
