Not sure. I am not at all knowledgeable in kernel compilation.
I did what I did last time by rigorously following the
explanations on
https://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official
So should I start again with the same basic sources as obtained
by yesterday's "apt-get source linux" and then call
"bash debian/bin/test-patches ../newpatch"
where "newpatch" would be a file containing the final lines
from that webpage, i.e.:

If so, I could start that experiment tonight and have a look
at the result tomorrow morning.
