Subject: ALSA: hda/realtek - Make dock sound work on ThinkPad L570
From: Dennis Wassenberg <dennis.wassenberg@xxxxxxxxxxx>
commit e4c07b3b66b7d6a24c2fe3b1ddeff5cd9b378b3a upstream.
One version of Lenovo Thinkpad T570 did not use ALC298
(like other Kaby Lake devices). Instead it uses ALC292.
In order to make the Lenovo dock working with that codec
the dock quirk for ALC292 will be used.
