[PATCH] kernel-doc: Update script to find more "Return:" sections

[Joe Perches <joe@perches.com>]

Many kernel-doc return description sections headers
use variants of the "Return:" section prefix.

(some or maybe even most of these aren't in
 kernel-doc sections, but many are)

$ git grep -E -i "^\s*\*\s*return[s]?:"| \
  cut -f2- -d":" | awk '{print $1 $2}' | \
  sort | uniq -c
    121 *return:
    838 *Return:
    778 *RETURN:
    191 *returns:
   1965 *Returns:
    603 *RETURNS:

Rather than change all of the variants to the
canonical "Return:", adapt the script to accept
case insensitive "Return:" and "Returns:"

I don't know that this actually works.
It does seem right though.

Randy?  Rob?  Can you test this please?
