From 5fc16cc4f3044551587dfee8e12422cbf59303e8 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 11 Nov 2015 08:11:16 +0200 Subject: [PATCH] Bluetooth: Add stubs for synchronous HCI request functionality Prepare hci_request.c to have code for doing synchronous HCI requests, such as LE scanning or advertising changes. The necessary work callbacks will be set up in hci_request_setup() and cleaned up in hci_request_cancel_all(). The former is used when an HCI device get registered, and the latter each time it is powered off (or unregistered).
