device_bind_driver(9)

📦 version 7.3.1, in nixpkgs unstable

💖 device_bind_driver(9) 💖

okay so bestie, welcome to the device_bind_driver(9) page — yes that's the whole title, it's from the Kernel API Manual, and it's literally about marrying a driver to a single device 🎀

✨ NAME ✨

device_bind_driver — bind a driver to one device. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

int device_bind_driver (struct device *dev );

🌸 ARGUMENTS 🌸

  • dev — the device. your main character device, the one getting a driver 🫶

🔥 DESCRIPTION 🔥

So this one lets you manually attach a driver to a device. very hands-on, very DIY ✨

important!! the caller must have already set dev->driver before calling. like, that's on you, not on this function. no cap.

Also lowkey crucial: this function does not modify the bus reference count. so please, verify that it's accounted for before you call this 🙈. (good news tho — it is ok to call with no other effort from a driver's probe method 👑)

And one more thing, and this one's non-negotiable: this function must be called with the device lock held 🔒 like. held. held-held. don't be out here calling it unlocked, that's not the vibe at all 💀

alsooo callers should prefer to use device_driver_attach instead. it's giving "this one still works but the newer one ate" 😭
