There is a newer version of this series
[PATCH v5 12/14] drm/mediatek: Sort OVL adaptor components in alphabetical order
Posted by Hsiao Chien Sung 1 year, 4 months ago 
- Rename OVL_ADAPTOR_TYPE_RDMA to OVL_ADAPTOR_TYPE_MDP_RDMA
  to align the naming rule of mtk_ovl_adaptor_comp_id.
- Sort components' names in alphabetical order
- Sort device table in alphabetical order
- Add sentinel to device table

The lines is > 80 columns.

https://www.kernel.org/doc/html/latest/process/coding-style.html#breaking-long-lines-and-strings

Actually, there are other lines in this file greater than 80, but IMHO, 
it isn't a reason to continue to do that.

After that, everything looks fine for me.
