From f22525700b2ae34eb97a29a91e2eee902062b484 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 18 Nov 2015 12:49:20 +0200 Subject: Bluetooth: Move advertising instance management to hci_request.c This paves the way for eventually performing advertising changes through the hdev->req_workqueue. Some new APIs need to be exposed from mgmt.c to hci_request.c and vice-versa, but many of them will go away once hdev->req_workqueue gets used.
