Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The `irq_type` method on `IrqVector` is missing the `#[inline]` attribute, which is required by the subsystem guidelines for small forwarding functions in abstractions.

--- Patch [5]: [PATCH v2 5/5] rust: pci: expose the allocated interrupt type ---
commit 2729ea5a5c9bd73b2db961974f58b91749e6fbc9
Author: Danilo Krummrich <dakr@kernel.org>

rust: pci: expose the allocated interrupt type

This commit adds irq_type() methods to IrqVectorRegistration and IrqVector to
wrap the pci_irq_type() C function. This allows drivers to query the interrupt
type rather than assuming which type the PCI core selected.

[Severity: Low]
This isn't a bug, but should this method have an #[inline] annotation?

The Rust subsystem guidelines specify that small or forwarding functions in
abstractions should be annotated with #[inline]. Since this just forwards to
self.reg.irq_type(), adding the annotation would ensure it aligns with the
coding guidelines.
