Subject: [PATCH] staging: rtl8188eu: Remove code valid only for 5 GHz
Git-commit: 8d42daff47cecc69de0d3fb2a487ef5971fd6938
Patch-mainline: v4.20-rc1
References: FATE#326906

Remove code that is only valid for channels > 14.
This addresses the below TODO item.

- find and remove remaining code valid only for 5 GHz. Most of the obvious
  ones have been removed, but things like channel > 14 still exist.
