parse-maintainers: Add section pattern sorting
Section [A-Z]: patterns are not currently in any required sorting order. Add a specific sorting sequence to MAINTAINERS entries. Sort F: and X: patterns in alphabetic order. The preferred section ordering is: SECTION HEADER M: Maintainers R: Reviewers P: Named persons without email addresses L: Mailing list addresses S: Status of this section (Supported, Maintained, Orphan, etc...) W: Any relevant URLs T: Source code control type (git, quilt, etc) Q: Patchwork patch acceptance queue site B: Bug tracking URIs C: Chat URIs F: Files with wildcard patterns (alphabetic ordered) X: Excluded files with wildcard patterns (alphabetic ordered) N: Files with regex patterns K: Keyword regexes in source code for maintainership identification Miscellaneous perl neatening: - Rename %map to %hash, map has a different meaning in perl - Avoid using \& and local variables for function indirection - Use return for a little c like clarity - Use c-like function call style instead of &function Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
