[PATCH v2 0/2] rust: pci: don't probe() VFs in nova-core

[John Hubbard]

Changes in v2:

1) Completely rewrote the series, using Danilo's suggested approach of
"driver supports VF probing or not": the PCI driver core will skip
probing any device's VFs if the driver has coded itself as "not
supporting VFs".

2) Included Joel's clarification, as a comment in the code, about what
happens if VFs are probed.

As with v1 [1], I've based this on top of today's driver-core-next [2],
because the first patch belongs there, and the second patch applies
cleanly to either driver-core-next or drm-rust-next. So this seems like
the easiest to work with.
