With this patch callback functions can be registered to the
btd_adapter struct. The functions are then called when the powered
state of the adapter changes, with a boolean argument indicating
the new state. The reason for adding the functionality is that the
Maemo6 MCE plugin needs to be notified when the adapter is powered
on or off.

Subject: [PATCH] Add mode callback to btd_adapter
With this patch callback functions can be registered to the
btd_adapter struct. The functions are then called when the powered
state of the adapter changes, with a boolean argument indicating
the new state. The reason for adding the functionality is that the
Maemo6 MCE plugin needs to be notified when the adapter is powered
on or off.
