Hello dear developer,
since this patch has been around for years already and mentioned
multiple times on bugzilla, I'll try this way to communicate it. I never
posted a patch before and tried to follow the rules on the
https://wireless.wiki.kernel.org/ website.
The card is build in Samsung Galaxy Books and not usable without the patch.
Information about the card:

It would be great if you could apply the patch since no Linux has
wireless on those machines without it.
Kind regards,

The same country number CTRY_KOREA_ROC(410) cannot be used for different
regDomainPairs.
Thanks,
Peter

Hello Peter,
thanks for the information and the very quick answer!
When I saw that in the patch, I had the same question, but it still
worked. I have to admit that I copied it without knowing why it works.
Who defines the codes? Is it possible to set it to CTRY_KOREA_ROC4 which
is not in use yet? In that case drivers/net/wireless/ath/regd.h also
would need an additional entry line after row 128
CTRY_KOREA_ROC4 = 413,
413 apparently is not in use yet.
Cheers,
Andreas

For the upstream reviewers, you need to add a root cause analysis(why
the error happens) and about how your patch fixes the problem. Take a
read
https://www.kernel.org/doc/html/latest/process/submitting-patches.html#
for about submitting patches and follow the instruction, otherwise your
patch maybe not getting reviewed by the maintainer.
In addition to that, you said
"mentioned multiple times on bugzilla",
hence it'd be good if you add the bugzilla link, so that people
understand the history.
Peter
