## Summary - fix the guard in `pci_epc_map_msi_irq()` to reject a NULL EPC or missing `map_msi_irq` callback - reject out-of-range endpoint function numbers before invoking the controller op ## Why `pci_epc_map_msi_irq()` currently uses `&&` between the EPC NULL check and the callback check. That dereferences `epc` when it is NULL, and it lets a valid EPC with no `map_msi_irq` callback pass through to a NULL function call. The surrounding EPC wrappers also validate `funcno` before dispatching to controller operations, so this helper now follows the same input-validation pattern. ## Testing - `git diff --check origin/master...HEAD` - `git show --stat --check --format=fuller HEAD` - Not run: local NuttX build, because this Windows workstation does not have the required C build toolchain installed. -- This is an automated message from the Apache Git Service.
