Ard Biesheuvel 3ab7511eaf ALSA: hda - allow 40 bit DMA mask for NVidia devices
Commit 49d9e77e72 ("ALSA: hda - Fix system panic when DMA > 40 bits
for Nvidia audio controllers") simply disabled any DMA exceeding 32
bits for NVidia devices, even though they are capable of performing
DMA up to 40 bits. On some architectures (such as arm64), system memory
is not guaranteed to be 32-bit addressable by PCI devices, and so this
change prevents NVidia devices from working on platforms such as AMD
Seattle.

Since the original commit already mentioned that up to 40 bits of DMA
is supported, and given that the code has been updated in the meantime
to support a 40 bit DMA mask on other devices, revert commit 49d9e77e72
and explicitly set the DMA mask to 40 bits for NVidia devices.
