If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit ef4da45828603df57e5e21b8aa21a66ce309f79b upstream. VT1802 codec provides the invalid connection lists of NID 0x24 and 0x33 containing the routes to a non-exist widget 0x3e. This confuses the auto-parser. Fix it up in the driver by overriding these connections.
