✨ comedi_to_pci_dev(9) — Kernel API Manual ✨

okay bestie, welcome to the comedi_to_pci_dev(9) page from the Kernel API Manual — it’s the tiny helper that gets you the PCI device attached to a COMEDI device, and it’s giving “one job, done correctly.” 🎀

🌸 NAME 🌸

comedi_to_pci_dev — get the PCI device attached to a COMEDI device

🦋 SYNOPSIS 🦋

struct pci_dev * comedi_to_pci_dev (struct comedi_device *dev );

💖 ARGUMENTS 💖

• dev — COMEDI device.

✨ DESCRIPTION ✨

So the deal is: assuming dev->hw_dev is non-NULL, it is assumed to be pointing to a a struct device embedded in a struct pci_dev. Yes, the “a a” is literally in the original — we’re preserving the lore, no cap. 😭

👑 RETURN 👑

Attached PCI device if dev->hw_dev is non-NULL. Return NULL if dev->hw_dev is NULL.
