I can reproduce the issue on next-20201002 on my Raspberry Pi 4 just by
booting it up. As soon as I apply this patch, all warnings disappear. I
asked the original reporters to test if the patch resolves the issue for
them but I figured more visibility on this, the sooner. The commit
message might need to be revised if this turns out to be the case to
make it more apparent that it has a user visible issue, rather than just
a QoL fix.
Additionally, it seems like the patch is missing some reviewed by tags
from Kees, Sedat, and myself. Feel free to add a
