- Fix error in getACDB() when reading battery temperature:
Return value of get_batt_temp() has changed and calling code must be corrected.
- Fix handling of echo cancellation and noise reduction for car kits:
doAudioRouteOrMute() should not force SND_DEVICE_BT_EC_OFF sound device if
current device is SND_DEVICE_CARKIT.
