This is related to https://bugzilla.kernel.org/show_bug.cgi?id=221216, I
attached changed file, sorry again for this is not actual git patch, I
made this off repo as an quick test fix, I tried make patch from diff,
but it wouldn't apply for some reason. I added 2 lines on 596 and 597.
Thanks,
Vyacheslav

That's odd, did you take a look at the documentation for how to make a
patch? Take a look at Documentation/process/submitting-patches.rst

No need to attach it, just use 'git send-email' to send it directly.
Also, some comments on the patch:

You need to have some changelog text, we can't take it without any
wording.

The list should be sorted by id. Please put this in the proper place in
the list.

Close, this should actually be the subject line, you forgot to have one
entirely in your email :)
And can you wrap the changelog text at 72 columns, like your editor
should have asked you to when making this change? If you run your patch
through scripts/checkpatch.pl before sending it, it should tell you
about these types of things.

Not a problem. There was some minor issues with this one (prefix of
subject, and no v2 information), but I've fixed it up and applied it
now, thanks!
