okay bestie, welcome to the prm_unregister(9) page — yes, that's the Kernel API Manual energy. grab a strawberry 🍓 and let's get into it.

💖 NAME 💖

prm_unregister — unregister per-SoC low-level data & function pointers. literally that's the whole vibe. periodt.

---

🦋 SYNOPSIS 🦋

int prm_unregister (struct prm_ll_data *pld );

---

🎀 ARGUMENTS 🎀

• pld — the low-level per-SoC OMAP PRM data & function pointers you wanna unregister. hand it over, bestie 🫶

---

🔥 DESCRIPTION 🔥

so this is the function that unregisters per-SoC low-level OMAP PRM data and function pointers that were previously registered with prm_register. yes, it's giving cleanup era ✨

important heads-up: the caller may not destroy any of the data pointed to by pld until this function returns successfully. no cap, do not touch/free/destroy that data early — wait for the successful return. 💀

it returns 0 upon success, or -EINVAL if pld is NULL or if pld does not match the struct prm_ll_data * previously registered by prm_register. that's the whole return value tea. 🫖
