From e9b9cfa1575e37cb2dbb5534aeaaa16814228887 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sat, 7 Jan 2012 15:47:22 +0100 Subject: Bluetooth: Remove HCI-owner field After unregistering an hci_dev object a bluetooth driver does not have any callbacks in the hci_dev structure left over. Therefore, there is no need to keep a reference to the module. Previously, we needed this to protect the hci-destruct callback. However, this callback is no longer available so we do not need this owner field, anymore. Drivers now call hci_unregister_dev() and they are done with the object.
