get_maintainer: fix unexpected behavior for path/to//file (double slashes)
get_maintainer behaves differently if there is a double sequential forward
slash in a filename because the total number of slashes in a filename is
used to match MAINTAINERS file patterns.
For example:
(with double slash)
$ ./scripts/get_maintainer.pl -f drivers/gpu/drm//lima
David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS,commit_signer:3/42=7%)
Qiang Yu <yuq825@gmail.com> (commit_signer:36/42=86%,authored:24/42=57%)
Vasily Khoruzhick <anarsoul@gmail.com> (commit_signer:26/42=62%)
Krzysztof Kozlowski <krzk@kernel.org> (commit_signer:5/42=12%,authored:5/42=12%)
Emil Velikov <emil.velikov@collabora.com> (commit_signer:4/42=10%)
dri-devel@lists.freedesktop.org (open list:DRM DRIVERS)
linux-kernel@vger.kernel.org (open list)
(without double slash)
$ ./scripts/get_maintainer.pl -f drivers/gpu/drm/lima
Qiang Yu <yuq825@gmail.com> (maintainer:DRM DRIVERS FOR LIMA)
David Airlie <airlied@linux.ie> (maintainer:DRM DRIVERS)
Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS)
dri-devel@lists.freedesktop.org (open list:DRM DRIVERS FOR LIMA)
lima@lists.freedesktop.org (moderated list:DRM DRIVERS FOR LIMA)
linux-kernel@vger.kernel.org (open list)
So reduce consecutive double slashes to a single slash
by using File::Spec->canonpath().
from: https://perldoc.perl.org/File/Spec/Unix.html
canonpath()
No physical check on the filesystem, but a logical cleanup of a path. On
UNIX eliminates successive slashes and successive "/.".
