Just an FYI, I've been tracking down a bug that was causing the debian bullseye installer to immediately crash and reboot the xen domU and bisected it to this commit. It appears that the Xen Virtual Keyboard driver ( and at least one other, probably more ) were always broken and failed to trigger the udev event, but this was never noticed. When this patch returned the error code, it caused the d-i init scripts triggering coldplug events to fail, which caused init to bail out, causing a kernel panic.
In the future, when fixing error returns like this, could you please add a big fat printk so that hopefully things that always should have failed but didn't and now do can get noticed and fixed more quickly.
