✨ NAME ✨

snd_pci_quirk_lookup — look up a PCI SSID quirk list 🔍💖

like, it's giving "search the list, find the match" energy. no cap.

🌸 SYNOPSIS 🌸

const struct snd_pci_quirk * snd_pci_quirk_lookup (struct pci_dev *pci ,
       const struct snd_pci_quirk *list );

literally returns a const struct snd_pci_quirk * and takes two args. that's it, that's the whole signature, slay 💅

🎀 ARGUMENTS 🎀

• pci — the pci_dev handle 🖥️ like, your actual PCI device bestie, the one you're curious about
• list — the quirk list, and it's terminated by a null entry ⚠️ (yes, that null entry is doing main character work — don't forget it)

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function looks through the given quirk list and finds a matching entry with the same PCI SSID. that's the whole mission.

AND listen — when subdevice is 0, all subdevice values may match 👀 so like, subdevice 0 is the wildcard friend who gets along with everyone.

it returns the matched entry pointer ✨ or NULL if nothing matched 😭 (iykyk, always check for NULL).
