int marvell_init_one (struct pci_dev *pdev , const struct pci_device_id
*id );

that's the whole signature, no cap. returns an int, takes a struct pci_dev * and a const struct pci_device_id *, and she's done 💜

that's it, that's the vibe — the PCI layer calls her, she does her thing, everyone moves on. no need to overthink it, bestie 🙈

LOCKING: Inherited from PCI layer (may sleep).
