I did, yes.

That was my assumption but with very little information provided I'm
reluctant to take the patch.
For example if the kernel with which the issue was triggered is provided
by a separate layer it seems like this patch belongs in a bbappend in
the same layer, no?
If I can build for qemu machines without this patch will not the
application of the patch have a negative effect?
Sure, I can likely answer each of these questions myself if I spend some
CPU cycles running builds but
