of_genpd_remove_last(9)

✨ NAME ✨

okay so welcome to the Kernel API Manual bestie 💖 — this page is of_genpd_remove_last(9), and what it does is literally right there in the name: Remove the last PM domain registered for a provider. slay.

---

🌸 SYNOPSIS 🌸

struct generic_pm_domain * of_genpd_remove_last (struct device_node *np
);

that's the whole signature, no cap 💅

---

🎀 ARGUMENTS 🎀

• np — a pointer to the device node that's associated with the provider 🫶

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: it goes and finds the last PM domain that a particular provider added, and then it removes that PM domain from the list of PM domains. the provider gets identified by the 'provider' device structure that gets passed in 👑

and here's the ✨important caveat✨ (do not skip this, i'm serious): the PM domain will only be removed if the provider associated with the domain has been removed. like, that's the condition. no provider-removal, no domain-removal. periodt. 🙈

on the way out it returns a valid pointer to struct generic_pm_domain on success, or ERR_PTR on failure. so like... check your pointers, bestie 😭

ngl the "only removed if the provider has been removed" bit is the main character of this page — respect it or your PM domain is staying right where it is 😭
