Simple coding style changes to single file
drivers/staging/rtl8192u/ieee80211/rtl819x_HTProc.c
Given feedback on some of the comments, I truncated to the 80 character limit,
in code, (as opposed to function block comments). I have left a number of the
contentious comments as they are.
Another piece of feedback suggested using memset() instead of a loop to
initialise memory so I've added that change to the set.
Sorry having difficulty getting the full v3 patch set sent using git
send-email. Only one seems to be going out. Sorry about the noise.
Removed the unrequired braces from single statement blocks - Coding Style.

Changed a number of hard coded function names to use %s and __func__
Mailing list response suggest that there is a better method for debugging
using netdev_dbg(). I can't argue with that, but for the moment this change
will clear the checkpatch.pl Warning.

Where possible truncation of block comments to the 80 character length
preferred by the coding style.
In a previous version of this commit some of the comments were contentious so
those have not been touched in this version.
