[Mesa-dev] nouveau_vieux loading broken in 10.1

[Ilia Mirkin]

Hello,

Starting with

commit 7bd95ec437a5b1052fa17780a9d66677ec1fdc35

    dri2: Trust our own driver name lookup over the server's.

    This allows Mesa to choose to rename driver .sos (or split drivers),
    without needing a flag day with the corresponding 2D driver.

    v2: Undo the loader-only-for-dri3 change.

nouveau_vieux loading no longer works. I investigated a little, and it
looks like loader_get_pci_id_for_fd doesn't retrieve the pci id for
nouveau, and even if it did, there is no pci id map like there is for
other hardware.

I think the simplest solution is to make loader_get_driver_for_fd
return NULL for nouveau, which in turn would preserve the existing
logic of using the driver name provided by X.

Thoughts?
