Lemote A1004(Laptop) and A1205(All-In-One) use Conexant's hda codec, this patch make it usable: 1, Use 32-bit DMA as a workaround (Loongson has a hardware bug that it doesn't support DMA address above 4GB). 2, Modify patch_conexant.c to add Lemote specific code.

As Clemens already suggested, please split your patch. The addition of PCI ID, addition of the workaround in HD-audio controller code, and the modification to Conexant codec code are all different things.

Where is CONFIG_CPU_LOONGSON3 defined at all? This isn't found in the upstream Linus or linux-next tree.

In general, we don't accept such a static quirk any longer unless a special reason is given. Doesn't the auto-parser work for you?
thanks,
