The following commit should fix this issue:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e9c18ae6eb2b312f16c63e34b43ea23926daa398
Waiting for release_event in all three drivers introduced issues on release
as on_reset() hook is not always called. E.g. if the device was never
opened we will never get the completion.
Move the waiting code to hvutil_transport_destroy() and make sure it is
only called when the device is open. hvt->lock serialization should
guarantee the absence of races.
