Well, there is no Tested-By from either of us, so this isn't optimal.

I wished Arnd could have at least pinged me back regarding this. He knows I'm
actively maintaining arch/sh and I would like to properly test and review
such changes.

But I'm not doing this professionally, so I cannot be always there with 100%
capacity. Just pushing such changes in without any input from me defeats the
purpose of a maintainer.
