And to the original v10 there is a reply by Krzysztof;
see https://lore.kernel.org/linux-pwm/3d9e50db-19f0-43b3-8042-2f80a1e7b79e@=
linaro.org/ .

I'll mark the original and this resend as "changes-requested" in our
patchwork. Probably the most cooperative way to object is to send a v11
and point out the changes compared to v10.

Best regards
Uwe
