I've fixed this up & applied these 2 patches with minor tweaks to
mips-next for 4.19.

However FYI for next time - you shouldn't really add someone else's
Signed-off-by tag anyway. The tag effectively states that a person can
agree to the Developer's Certificate of Origin for this patch (see
Documentation/process/submitting-patches.rst), and you can't agree that
on behalf of someone else. Generally a maintainer should add this tag
for themselves when they apply a patch.

Anyway, I think we should reserve the Singed-off-by tag for patches that
quell fires. ;)

Thanks,
    Paul
