Hmm, I don't recall reviewing or acking this patch. I do recalling doing

https://lore.kernel.org/linux-pwm/Y9len4GinXQ101xr@spud/

Please remove these from your next submission, I don't have any knowledge
of this driver nor do I maintain it, thanks.

Should there be a Co-developed-by for Vincent?

Thanks,
