Subject: [PATCH 5.4 132/214] ALSA: hda/realtek: Add model alc298-samsung-headphone

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

[ Upstream commit 23dc958689449be85e39351a8c809c3d344b155b ]

The very quiet and distorted headphone output bug that afflicted my
Samsung Notebook 9 is appearing in many other Samsung laptops. Expose
the quirk which fixed my laptop as a model so other users can try it.
