💅 acpi_dev_get_pci_dev(9) — Kernel API Manual 🎀

okay so bestie, welcome to the glow-up of the <pink>acpi_dev_get_pci_dev</pink> page from the Kernel API Manual ✨ this one's short and sweet, literally a little matchmaker function that hooks your ACPI device up with its PCI bestie 💖

✨ NAME ✨

acpi_dev_get_pci_dev — get a struct pci_dev for a given ACPI device 🫶

🌸 SYNOPSIS 🌸

struct pci_dev * acpi_dev_get_pci_dev (struct acpi_device *adev );

🦋 ARGUMENTS 🦋

• adev — your target ACPI device, the main character in question 👑

💜 DESCRIPTION 💜

so what it does is: find the PCI device associated with adev, if any, and bump up its reference counter ✨ like it's giving matchmaker energy, it finds the PCI partner and then makes sure the refcount knows somebody's holding onto it now 🔥

heads up bestie 😭 callers are responsible for dropping the PCI device reference obtained by this function. no cap, that's on you. don't just walk away from it 💀

🌈 RETURN 🌈

the struct pci_dev pointer of a reference-counted PCI device on success 🌟 or NULL on failure 🙈 that's the whole vibe check.
