[PATCH] ALSA: hda/realtek: Fix conflicting PCI SSID 17aa:386f for Lenovo Legion models

[Takashi Iwai <tiwai@xxxxxxx>]

Unfortunately both Lenovo Legion Pro 7 16ARX8H and Legion 7i 16IAX7
got the very same PCI SSID while the hardware implementations are
completely different (the former is with TI TAS2781 codec while the
latter is with Cirrus CS35L41 codec).  The former model got broken by
the recent fix for the latter model.

For addressing the regression, check the codec SSID and apply the
proper quirk for each model now.

Fixes: 24b6332c2d4f ("ALSA: hda: Add Lenovo Legion 7i gen7 sound quirk")
