ccw_driver_unregister(9)

💅 ccw_driver_unregister(9)

okay so real talk, bestie — this is a page from the Kernel API Manual and it's about ccw_driver_unregister(9), like, the kernel-level manual name right there in the corner of the page. it's short, it's sweet, and it does exactly one thing. let's get into it 🎀

---

✨ NAME ✨

ccw_driver_unregister — deregister a ccw driver

like, that's it. that's the whole job. she deregisters. she leaves. she does not stay. 💅

---

🌸 SYNOPSIS 🌸

void ccw_driver_unregister (struct ccw_driver *cdriver );

no return value, no drama, just vibes and a pointer. (yes the space before the closing paren is canon, do not @ me 🫶)

---

🦋 ARGUMENTS 🦋

• cdriver — the driver to be deregistered. like, the actual one you want gone from the registry. hand her the driver, she handles the rest ✨

---

💖 DESCRIPTION 💖

so here's the tea: this function is mainly a wrapper around driver_unregister. that's literally the whole description, no cap. she's a cute little shortcut so you don't have to call the underlying thing yourself. lowkey iconic of the kernel devs to give us a one-liner tbh 😭
