Subject: [PATCH v2 0/3] rust, nova-core: PCI Class, Vendor support

Hi Danilo and all,

I'm quite pleased with how this ended up! The new code in nova-core is
nicely readable, and now we've paved the way for other PCI device drivers
as well.

Quite a few "use kernel::bindings" lines were removed, as a result.

Changes since v1:

1) Use the pci_device_table for filtering, instead of open-coding
   filters in the .probe() callback.

2) Add PCI Class (class, subclass, implementation) and PCI Vendor to
   Rust for Linux.

3) Rebased onto the latest nova-next branch, which is here:
    https://gitlab.freedesktop.org/drm/nova.git

v1 is here:
    https://lore.kernel.org/20250813232859.224316-1-jhubbard@nvidia.com
