[pulseaudio-discuss] [RFCv3 40/43] bluetooth: Fail to load driver is discovery module is not loaded

[jprvita]

From: João Paulo Rechi Vita <jprv...@openbossa.org>

For quite some time now the device driver module doesn't work well
without the discovery module, so for the BlueZ 5 support we'll prevent
the device driver module to be loaded if the discovery module is not
loaded.
