get_maintainer.pl: find maintainers for removed files
Geert Uytterhoeven [Fri, 22 Feb 2013 00:43:12 +0000 (16:43 -0800)]
For removed files, get_maintainer.pl doesn't find any maintainers (besides
the default linux-kernel@vger.kernel.org), as it only looks at the "+++"
lines, which are "/dev/null" for removals.  Fix this by extending the
parsing to the "---" lines.

E.g. for the two line test patch below the real score maintainers will now
be found:

    --- a/arch/score/include/asm/dma-mapping.h
    +++ /dev/null
