Subject: [PATCH] get_maintainer: Extend matched name characters in maintainers_in_file()

Extend the regexp matching name characters to cover Unicode blocks Latin
Extended-A and Extended-B.
Fixes 'scripts/get_maintainer.pl -f' for
'Documentation/devicetree/bindings/clock/apple,nco.yaml'.

Signed-off-by: Janne Grunau <j@...nau.net>

This still excludes Greek and Cyrilic characters which should be
expected in names as well. I tried to use '\p{L}' to match all Unicode
letters but couldn't get it to work. Feel free understand this as bug
report with an incomplete fix.

best regards,
Janne
