From 9b74246f3a074b6072fa81002805ceaefb87a013 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 14 Oct 2013 16:20:03 +0300 Subject: [PATCH] Bluetooth: Reorganize set_connectable HCI command sending This patch moves all the decisions of which HCI commands to send (or not to send) to the code between hci_req_init() and hci_req_run() this allows us to further extend the request with further commands but still keep the same logic of handling whether to return a direct mgmt response in the case that no HCI commands were sent.
