It's likely due to this recently applied commit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/c...
Maybe commit 46e85af0cc53 ("driver core: platform: don't oops in platform_shutdown() on unbound devices") fixes this issue, but I didn't test it.
Thanks, I'll go fix this up again.
