[Xen-devel] [PATCH] get_maintainer: fix perl 5.22/5.24 deprecated/incompatible "\C" use

[Olaf Hering <olaf@xxxxxxxxx>]

From: Joe Perches <joe@xxxxxxxxxxx>

Perl 5.22 emits a deprecated message when "\C" is used in a regex.  Perl
5.24 will disallow it altogether.

Fix it by using [A-Z] instead of \C.

 [ Upstream commit ce8155f7a3d59ce868ea16d8891edda4d865e873 ]
