| H A D | hci_core.h | 4c724c71 Sat Jan 07 08:47:23 CST 2012 David Herrmann <dh.herrmann@googlemail.com> Bluetooth: Correctly take hci_dev->dev refcount
The hci_dev->dev device structure has an internal refcount. This
refcount is used to protect the whole hci_dev object. However, we
currently do not use it. Therefore, if someone calls hci_free_dev() we
currently immediately destroy the hci_dev object because we never took
the device refcount.
This even happens if the hci_dev->refcnt is not 0. In fact, the
hci_dev->refcnt is totally useless in its current state. Therefore, we
simply remove hci_dev->refcnt and instead use hci_dev->dev refcnt.
This fixes all the symptoms and also correctly integrates the device
structure into our bluetooth bus system.
