[PATCH] checkpatch: Remove cvs keyword check

[Kari Argillander <kari.argillander@gmail.com>]

Time has pass and we do not need these anymore as almost all people are
using git now days. Those who use cvs for kernel development probably
will handle cvs pretty well already so this check is not needed anymore.

If someona nack about this can you also help howto fix false alarms in
fs/ntfs3/ by this cvs check. We need to use $Log in comments as it is
real name. I'm also triccered to see these false alarms. I'm not
familier with perl regex syntax and do not really understand what we
are trying to do here. Maybe also because I do not know CVS very well.

I can do patch or someone else can do it. I just want this "problem"
away as it has been sitting my todo list too long.

-  **CVS_KEYWORD**
-    Since linux moved to git, the CVS markers are no longer used.
-    So, CVS style keywords ($Id$, $Revision$, $Log$) should not be
-    added.
-
   **DEFAULT_NO_BREAK**
     switch default case is sometimes written as "default:;".  This can
     cause new cases added below default to be defective.
