device

EFI_HANDLE chained_protocol::device

Target device handle.

This is the uppermost handle on which the same protocol instance is installed as we find on the loaded image's device handle.

We match against the protocol instance (rather than simply matching against the device handle itself) because some systems load us via a child of the underlying device, with a duplicate protocol installed on the child handle.

We record the handle rather than the protocol instance pointer since the calls to DisconnectController() and ConnectController() may end up uninstalling and reinstalling the protocol instance.
