[PATCH 1/4] staging: rtl8188eu: Remove code valid only for 5 GHz

[Michael Straube]

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.
