Krzysztof? You need to Cc him first... I mean, the other Krzysztof, or
whoever is needed to be Cc-ed.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

Best regards,
Krzysztof

And now please think... how can he comment on this one liner since he
did not receive anything else? Since he was not Cced on original
submission, he has nothing from this thread in inbox. Only this one
email with one line above.

How any reviewer can understand something without context? This does not
work like that. You cannot just add someone to Cc to one line comment
and expect that maintainers will start looking for your patches so they
can perform the review, just because you need it.

You must resend your patchset following Linux kernel process - Ccing all
respective maintainers, not just some.

You have experienced contributors and maintainers in Xilinx/AMD, so
please talk with them how the process should look like.

Best regards,
Krzysztof
