[PATCH 12/56] Revert "bluetooth: Parse the tree returned by ObjectManager"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>

This reverts commit c4bd51a34547ed0991ff3c7219c2d5de49669ca8.

This is part of the reversion of BlueZ 5 support so it can be added back
in a separate set of modules. This makes the code easier to maintain and
decrease PulseAudio's binary size.
