[PATCH] checkpatch: don't encourage new code to use "networking" style comments

[Brian Norris]

Our glorious leader has made his opinion known [1]: the "networking"
comment style is not useful for new code. While the same rules as usual
still apply -- e.g., don't unnecessarily churn existing code, and follow
existing practice within files -- that doesn't mean that checkpatch
should be enforcing that for entire directories. Among other reasons,
this can cause automatic patch generators to do the exact wrong thing:
convert perfectly good existing code into the "networking style", just
because it's in a similar directory.

And funny side note from that thread:

Ingo:
"Btw., as a historic reference, there is nothing sacred about the
'networking comments coding style': I was there (way too many years ago)
when that comment style was introduced by Alan Cox's first TCP/IP code
drop, and it was little more than just a random inconsistency that
people are now treating as gospel..."
