If anyone has any objections, please let me know. ------------------ From: Maxim Mikityanskiy [ 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.
