💅 cm_unregister(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual entry for cm_unregister(9) — this is the little cleanup-era icon that unregisters per-SoC low-level data & function pointers. no cap, it’s giving “put the special per-SoC stuff back where you found it” energy. 🎀

✨ NAME ✨

cm_unregister — unregister per-SoC low-level data & function pointers 🦋

---

🌸 SYNOPSIS 🌸

int cm_unregister (const struct cm_ll_data *cld );

---

🎀 ARGUMENTS 🎀

• cld — the low-level per-SoC OMAP CM data & function pointers you want to unregister, bestie. literally the whole struct cm_ll_data situation. 💖

---

🦋 DESCRIPTION 🦋

so here’s the vibe: cm_unregister unregisters the per-SoC low-level OMAP CM data and function pointers that were previously registered with cm_register. 🔥

important one, fr fr: the caller may not destroy any of the data pointed to by cld until this function returns successfully. do not skip that part. 😭

it returns 0 upon success, or -EINVAL if cld is NULL or if cld does not match the struct cm_ll_data * previously registered by cm_register. periodt. 👑
