Thanks for picking up that issue. I confirm this fix the "problem".

To give some more details, the problem for Debian is that it appears as
an error, with the line in red in dmesg or journalctl. However we would
like to be able to provide a kernel with such drivers enabled so that
users with a camera can just use an overlay or patch their device tree.
