Sophon Zhang 8d7b3e41ff rust: pci: reject IRQ vector indices that do not fit in u32 ... IrqVectorRegistration::index() accepts a usize, but pci_irq_vector() takes an unsigned int. On 64-bit architectures, casting an index larger than u32::MAX wraps it before the PCI core can validate it. In particular, u32::MAX + 1 becomes zero and can resolve to the first allocated vector. Use a checked conversion and return EINVAL when the index cannot be represented by the C API.
