Bluetooth: Use struct delayed_work for HCI command timeout
Since the whole HCI command, event and data packet processing has been migrated to use workqueues instead of tasklets, it makes sense to use struct delayed_work instead of struct timer_list for the timeout handling. This patch converts the hdev->cmd_timer to use workqueue as well. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
