The device name problem is tracked in 217330, which I filed.

A bisection would definitely help me if you have time, otherwise I'll
get to it, but it's probably not going to be before a couple of weeks.

You can also test this patch on top of the latest kernel tree:
https://patchwork.kernel.org/project/linux-input/patch/20230531082428.21763-1-hadess@hadess.net/
although I don't expect it to make a difference.
