[PATCH] ALSA: hda/realtek: Add quirk for LG Gram 17ZD90R-EX79K

[빛나는황소]

From: Jabong Koo <safenine@gmail.com>

The internal speakers on the LG Gram 17ZD90R-EX79K remain silent,
while headphone output works normally.

The machine uses a Realtek ALC298 codec with PCI subsystem ID
1854:048b. Existing LG Gram subsystem IDs 1854:0488, 1854:0489 and
1854:048a use ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS, but 1854:048b is
missing from the quirk table.

Add the matching quirk for subsystem ID 1854:048b.

Tested successfully on Ubuntu HWE kernels 6.17.0-41-generic and
7.0.0-28-generic.

The patch looks malformed (with wrong spaces), likely due to your
mailer, so it can't be applied cleanly via git-am.
Please fix your mailer setup, and resubmit the fix.


thanks,

Never mind, I see that there was another fix submission by Aaron for
the very same device with the same quirk, and it was applied now.
