Please try to avoid changing code merely to appease checkpatch.

What is the value of the last s?
When is a specific index of the IEs array actually used?

Mere renaming may be removing useful markings.

(removing a lot of the rename blocks)

For instance, these consistent 12 and "- 12" uses may be better as some
alternate array.

etc...

Also this may be removing similarities between a few other realtek
staging drivers

$ git grep  "\[MAX_IE_SZ\]"
