[PATCH 01/13] Coding style changes to block comments
From: John Whitmore
Date: Mon May 14 2018 - 11:54:18 EST
The file drivers/staging/rtl8192u/ieee80211/rtl819x_HTProc.c has a lot of
coding style issues, this will be the first of many small patches which clear
up some, if not all, of the problems with the file.
