ALSA: hda: intel: Add Lenovo IdeaPad Z570 to probe denylist
[ Upstream commit
becc794c5e46f4dfca59f2385f78d83fc9e84700 ]
Lenovo IdeaPad Z570 with NVIDIA GeForce Ge 540M doesn't have sound on
the discrete GPU. The HDA controller in DGPU is disabled by BIOS, but
then reenabled by quirk_nvidia_hda(). The probe fails and ends up with
the "GPU sound probed, but not operational" error.
Add this laptop to DMI-based denylist to prevent probe early. DMI is
used, because the audio device has zero subsystem IDs, and this entry
would be too much, blocking all 540M chips:
PCI_DEVICE_SUB(0x10de, 0x0bea, 0x0000, 0x0000)
Also, this laptop comes in a variety of modifications with different
NVIDIA GPUs, so the DMI check will cover them all.
