Re: [PATCH v2 07/14] vfio/platform: Use open_device() instead of open coding a refcnt scheme

Platform simply wants to run some code when the device is first
opened/last closed. Use the core framework and locking for this.  Aside
from removing a bit of code this narrows the locking scope from a global
lock.
