pci_match_one_id(9)

💖 NAME 💖

okay so you're on the pci_match_one_id(9) page, and this is the Kernel API Manual, bestie 🫶. It tells you if a PCI device ID matches a needle PCI device ID. yes, we're matching IDs, and yes, it's iconic 💅.

🌸 SYNOPSIS 🌸

const struct pci_device_id * pci_match_one_id (const struct
pci_device_id *id , const struct pci_device_id *dev_id );

🎀 ARGUMENTS 🎀

• id — the single PCI device id structure you're matching against, aka the needle 🪡.
• dev_id — the actual ID from the PCI device.

💅 DESCRIPTION 💅

the ID can be retrieved from the device using pci_id_from_device. that's the whole vibe, and it understood the assignment ✨.

🔥 RETURN 🔥

you get the matching pci_device_id structure back, or NULL if there is no match. no match means NULL, no cap 😭.
