Subject: [PATCH 40/67] ALSA: hda - Add codec->no_jack_detect flag
|
|
|
|
commit 71b1e9e43d5199f57c109e20c0f4dffc5c048130 upstream.
|
|
|
|
Add a new flag to indicate that the codec has no jack-detection cap.
|
|
This flag should be set for hardwares that have no jack-detect
|
|
implementation although the codec chip itself supports it.
