Right, that changed with the conversion, but should look like the same
to userspace by following the "device" links. Not sure, why it was done
this way, the original conversion didn't change that, I think.

It's a bug sneaked in from another patch while merging. It prevents the
creation of the device link to construct the parent relationship.
It is:

If that doesn't work for you, let me know and I will contact the input
maintainer and see what we need to do.

Sure, that will just work, and also add some more information to sysfs
that may be needed in the future. I'm also not testing
CONFIG_SYSFS_DEPRECATED kernels for new udev releases anymore.
