[Qemu-devel] [PATCH 5/5] get_maintainer: add subsystem to reviewer output

[Paolo Bonzini <pbonzini@redhat.com>]

From: Joe Perches <joe@perches.com>

Reviewer output currently does not include the subsystem
that matched.  Add it.

Miscellanea:

o Add a get_subsystem_name routine to centralize this
