This 'hmm_device' API family was recently deleted from hmm:

mm: remove the struct hmm_device infrastructure
This code is a trivial wrapper around device model helpers, which
should have been integrated into the driver device model usage from
the start. Assuming it actually had users, which it never had since
the code was added more than 1 1/2 years ago.
This patch should use the driver core directly instead.
