Subject: device-restore: Split device restore database into two parts.
X-Git-Tag: v0.99.3~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ee97e57caf34576ba97cf3b6e7b51388442e3c2;p=platform%2Fupstream%2Fpulseaudio.git

device-restore: Split device restore database into two parts.

The device restore saves both the current port for a device, and the volume/mute/formats.
The latter three are really related to the device+port, not the device on it's own.

Thus we store just the port for a device in one key and the volume/mute/formats
under a different key that includes both the device and the port.
