ALSA: core: Fix SSID quirk lookup for subvendor=0
Some weird devices set the codec SSID vendor ID 0, and snd_pci_quirk_lookup_id() loop aborts at the point although it should still try matching with the SSID device ID. This resulted in a missing quirk for some old Macs. Fix the loop termination condition to check both subvendor and subdevice. Fixes: 73355ddd8775 ("ALSA: hda: Code refactoring snd_hda_pick_fixup()") Cc: <stable@vger.kernel.org> BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=215495 Link: https://lore.kernel.org/r/20220116082838.19382-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
