and the feedback I got from Jason was:

opened.. Lots of systems have TPMs but few use the userspace.."

so I changed this to allocate the WQ on first open. I think it makes
sense, but I leave it to you to decide.

If the reason is to not create a wq unless it's needed, shouldn't the
condition actually be first open with flag O_NONBLOCK?
