Subject[PATCH] kerneldoc: Convert error messages to GNU error message format
Editors like emacs and vi recognize a number of error message
formats. The format used by the kerneldoc tool is not recognized
by emacs. Change the kerneldoc error message format to the GNU
style such that the emacs prev-error and next-error commands can
be used to navigate through kerneldoc error messages. For more
information about the GNU error message format, see also
https://www.gnu.org/prep/standards/html_node/Errors.html.
