platform_match(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual page for platform_match(9) — literally here to bind platform device to platform driver. 💅✨

---

✨ SYNOPSIS ✨

int platform_match (struct device *dev , const struct device_driver *drv
       );

---

🎀 ARGUMENTS 🎀

• dev — the device. that's the device bestie 🫶
• drv — the driver. and this one is the driver 💖

---

🦋 DESCRIPTION 🦋

so here's the tea, no cap: platform device IDs are assumed to be encoded like this:

"<name><instance>"

where <name> is a short description of the type of device, like "pci" or "floppy", and <instance> is the enumerated instance of the device, like '0' or '42'. Driver IDs are simply "<name>". 🌈

so yeah — extract the <name> from the platform_device structure, and compare it against the name of the driver. Then return whether they match or not. that's the whole vibe check, periodt ✨🔥
