bus_remove_driver(9)

🦋 bus_remove_driver — the bus_remove_driver(9) page, kernel API manual edition ✨

okay bestie, so this is a page straight out of the kernel API manual (that's the manual name, we're not copying the header line, we're just saying it 💅), and it's literally about taking a driver off a bus. short page, but it ATE. let's go 🎀

---

🌸 NAME 🌸

bus_remove_driver — delete driver from bus's knowledge.

like, the bus is gonna forget this driver ever existed. not me doing a memory wipe on the bus 😭

---

✨ SYNOPSIS ✨

void bus_remove_driver (struct device_driver *drv );

no return value, it's void, it just does the thing and dips 🫶

---

💖 ARGUMENTS 💖

• drv — driver. that's it. that's the whole argument. a driver. the one you're about to remove. iconic non-explanation honestly 😌

---

🔥 DESCRIPTION 🔥

so here's the whole vibe, step by step:

1. Detach the driver from the devices it controls. yes, from all of them. it's giving breakup with the entire group chat 💀
2. Remove it from its bus's list of drivers. the bus no longer claims it. unfollowed, unfriended, blocked 🌈
3. Finally — the important bit — we drop the reference to the bus we took in bus_add_driver. goodbye ref, we hardly knew ye 🧚 lowkey this is the part that makes the whole thing balanced, so don't skip it, fr fr

ngl, this is the cleanup counterpart to bus_add_driver — you add it, you take the ref, and here you're handing that ref back. it's the circle of life but for kernel objects 💜
