media_entity_cleanup(9)

🌸 media_entity_cleanup(9) 🌸

okay so this is media_entity_cleanup(9) from the Kernel API Manual, and bestie, it's a cleanup function. Very demure, very mindful. 💅

---

✨ NAME ✨

media_entity_cleanup — free resources associated with an entity. That's the whole name-card, no cap. 🫶

---

🎀 SYNOPSIS 🎀

void media_entity_cleanup (struct media_entity *entity );

---

🦋 ARGUMENTS 🦋

• entity — entity where the pads belong. Yes, that's the official wording, and yes, we're keeping it exactly like that. 💖

---

🌈 DESCRIPTION 🌈

Okay so here's the tea: this function must be called during the cleanup phase after unregistering the entity. And rn — like, currently — it does nothing. Literally. That's not me being shady, that's just what the page says. 💀

Heads up, bestie: currently, it does nothing. Periodt.

Calling media_entity_cleanup on a media_entity whose memory has been zeroed but that has not been initialized with media_entity_pads_init is valid and is a no-op. So that specific situation? Valid. No-op. Iconic. ✨
