These should be:

Fixes: 2bbcaaee1fcb ("ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb")
Link: https://bugzilla.kernel.org/show_bug.cgi?id=208251

But I can fix those during commit.

There are basically two options now, either take this patch or revert commit 2bbcaaee1fcb:

https://patchwork.kernel.org/patch/11637341/

I prefer taking Mark's patch but I would appreciate if people could provide
testing feedback.

This fixes the issue for me. Please don't forget:
Reported-by: Roman Mamedov <rm@romanrm.net>

And if you want to add this:
Tested-by: Viktor Jägersküpper <viktor_jaegerskuepper@freenet.de>

These additional lines are mainly useful if the patch doesn't work for someone
else and they decide to report it, so hopefully Roman and I would receive the
report, too. And we already have three threads for this bug.

Thanks, I will. Or well, actually patchwork automatically does that :)
