It looks like your workflow of copy-pasting this into your
email client has turned the tabs in the patch into a single space
character.

This and possibly other issues (line-wrapping, wrong end-of-line type)
is why using git send-email is the preferred way to submit kernel
patches.

Maybe try using Brenton Simpson <appsforartists+kernel@xxxxxxxxxx>

for both the author and signed-off-by fields and then use
git send-email ?

Regards,

Hans

p.s.

Might be best to send the next attempt just to me, until you've
figured out a working email setup. And then once we have things
working, re-submit to the right people ?
