[PATCH 1/3] ALSA: hda/realtek: Fix DAC binding for Lenovo Legion Pro 7 16ARX8H

[Zhang Heng]

The Lenovo Legion Pro 7 16ARX8H (SSID 17aa:38a7) uses the TAS2781
I2C DAC. The generic ALC287_FIXUP_TAS2781_I2C quirk assumes two
speakers (0x14 and 0x17). It forcibly binds 0x14 to DAC 0x02, and
binds 0x17 and 0x21 to DAC 0x03.

However, this machine only has 0x17 as the speaker and lacks 0x14,
which leads to incorrect DAC binding. To fix this, chain the
alc295_fixup_asus_dacs() fixup before the generic quirk to ensure
the correct DAC routing for this hardware layout.
