Subject: [PATCH AUTOSEL 5.6 137/606] ALSA: hda/realtek: Add quirk for Samsung Notebook

From: Mike Pozulp <pozulp.kernel@...il.com>

[ Upstream commit 14425f1f521fdfe274a7bb390637c786432e08b4 ]

Some models of the Samsung Notebook 9 have very quiet and distorted
headphone output. This quirk changes the VREF value of the ALC298
codec NID 0x1a from default HIZ to new 100.

[ adjusted to 5.7-base and rearranged in SSID order -- tiwai ]
