[PATCH] ALSA: hda: Fix speakers on ThinkBook Plus G3 IAP

[Zhang Heng]

Lenovo ThinkBook Plus G3 IAP shares PCI SSID 17aa:3891 with Yoga Pro
7 14AHP9, but has a different codec SSID (0x17aa3875). Use
HDA_CODEC_QUIRK to select ALC287_FIXUP_CS35L41_I2C_2 and add ACPI
_SUB values 17AA3845/17AA3846 to the CS35L41 property table, since
the BIOS provides no _DSD.
