amba_device_unregister(9)

💅 amba_device_unregister(9) — the kernel API manual, but make it make sense 🎀

okay bestie, so you're in the amba_device_unregister(9) page of the Kernel API Manual, and honestly? it's giving "one function, big consequences." let's get into it ✨

---

🌸 NAME 🌸

amba_device_unregister — unregister an AMBA device, i.e. yeet it out of the device manager (lovingly) 🫶

---

🦋 SYNOPSIS 🦋

void amba_device_unregister (struct amba_device *dev );

that's it. that's the whole signature. no return value, no drama (well, some drama) 💅

---

🌈 ARGUMENTS 🌈

• dev — the AMBA device to remove. yes, that one. the one you want gone 🫡

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — this function removes the AMBA device you specified from the Linux device manager. bye bye, device 👋

and it's not a quiet exit either, because:

• all files associated with this object will be destroyed 💀
• device drivers get notified that the device has been removed 📣

so like, everyone finds out. no ghosting. main character energy only 💅

now the part you actually need to remember, bestie: the AMBA device's resources — including the amba_device structure itself — will be freed once all references to it have been dropped. so it's not instant-free, it's free-when-everyone's-done-with-it energy 🧚✨ lowkey important, highkey slay.
