From: Kailang Yang kailang@realtek.com Date: Fri, 2 Feb 2018 15:26:46 +0800 Subject: ALSA: hda/realtek - Enable Thinkpad Dock device for ALC298 platform

From: Kailang Yang kailang@realtek.com

commit 61fcf8ece9b6b09450250c4ca40cc3b81a96a68d upstream.

Thinkpad Dock device support for ALC298 platform. It need to use SSID for the quirk table. Because IdeaPad also has ALC298 platform. Use verb for the quirk table will confuse.
