devm_remove_action(9)

💅 devm_remove_action(9) — your girl's guide to taking back that action

okay so bestie, welcome to the Kernel API Manual ✨ like yes this is a manpage but make it cute — we're talking about devm_remove_action today and honestly it's giving "cleanup era" 🧹💖

---

✨ NAME ✨

devm_remove_action — removes previously added custom action 🫶

---

🎀 SYNOPSIS 🎀

void devm_remove_action (struct device *dev , void (*action)(void *) ,
       void *data );

that's the whole signature, no cap. three things go in, nothing comes back out (void, she says nothing) 💅

---

🌸 ARGUMENTS 🌸

• dev — Device that owns the action 👑 like this device is the main character, the action belongs to it
• action — Function implementing the action 🔥 the actual function pointer doing the work
• data — Pointer to data passed to action implementation 🍓 it gets handed straight to action

---

🦋 DESCRIPTION 🦋

Removes instance of action previously added by devm_add_action. both action and data should match one of the existing entries — like, fr fr, both of them, it's not gonna vibe-check just one 🙈

lowkey important: action and data both have to match an entry that's already there. don't come at it with half the pair 😭
