Hi,

Thanks for the patch. In such case don't forget to put "Reported-by" tag.

Reported-by: kbuild test robot <[email-masked]>
Reported-by: Arnd Bergmann <[email-masked]>

Similar fix was posted by Arnd recently:
https://patchwork.kernel.org/patch/9200311/

They achieve the same but I would prefer your solution of header
inclusion instead of forward declaration.

Rob, did you take Arnd's patch already?

Best regards,
Krzysztof
