Hello Walt,

I am not able to reproduce your problem with perl v5.4.21 on Debian Stretch:

$ scripts/get_maintainer.pl -f board/Marvell/dreamplug/
u-boot at lists.denx.de (open list)
$ perl scripts/get_maintainer.pl -m -r -l -f board/Marvell/dreamplug/
u-boot at lists.denx.de (open list)
$

I wonder why you are calling perl with -m -r -l.

The get_maintainer.pl script is maintained in the Linux kernel source
tree. So if you find any problem, please, send a mail

TO: Joe Perches <joe@perches.com> (maintainer:GET_MAINTAINER SCRIPT)
CC: linux-kernel at vger.kernel.org (open list)

As we have many MAINTAINERS files in subdirectories you are right in
that we should enable finding these. I will submit a patch.

Best regards

Heinrich

[U-Boot] [PATCH 1/1] scripts/get_maintainer.pl: enable find_maintainer_files

[Heinrich Schuchardt]

Many MAINTAINERS files are in subdirectories.
We should enable searching these.

These are missing Jason Cooper whom is the maintainer so neither is
correct but not sure why I have the bad divisor if you also have the
"+my $find_maintainer_files = 0;" setting.

From my uneducated understanding:

-m = maintainer
-r = reviewers
-l = mailing list

to get the email listings for each.

Sorry, I thought you had made the modifications.
