media_devic...ntity_notify(9)

💅 media_devic...ntity_notify(9) — like, the Kernel API Manual page, bestie 🎀

okay so this one lives in the Kernel API Manual and it's honestly such a clean little page — one function, two args, and a whole friend group of media_device functions in SEE ALSO. no cap.

✨ NAME ✨

media_device_unregister_entity_notify — Unregister a media entity notify callback 🫶

like, it's the undo button for a notify callback. the breakup text, but polite and in C.

---

🌸 SYNOPSIS 🌸

void media_device_unregister_entity_notify (struct media_device *mdev ,
   struct media_entity_notify *nptr );

returns void, so it literally gives you nothing back — no return value, no drama, no error code. it just does the thing. 💅

---

🦋 ARGUMENTS 🦋

• mdev — The media device. that's the main character here, the struct media_device everything hangs off of. 👑
• nptr — The media_entity_notify. yes bestie, that's the notify thing you're unregistering. the callback in question. literally the whole point. ⭐

💜 SEE ALSO 💜

the whole squad, in the order the page gives them — not me reordering, i would never 🙈:

• Kernel file ./include/media/media-device.h
• struct media_entity_notify(9)
• struct media_device_ops(9)
• struct media_device(9)
• media_device_init(9)
• media_device_cleanup(9)
• __media_device_register(9)
• media_device_register(9)
• media_device_unregister(9)
• media_device_register_entity(9)
• media_device_unregister_entity(9)

• media_device_pci_init(9)
• __media_device_usb_init(9)
• media_device_usb_init(9)
• media_set_bus_info(9)

quick vibe check for iykyk purposes: media_device_register_entity_notify(9) is the register side of this exact pairing — this page is the unregister half. that's the dynamic. 💀 🧚

and that's the page!! sign-off time: this cutie comes to you from ./include/media, dated October 2026, and it's giving "short manpage, big main character energy." slay, periodt, go unregister something responsibly. 🌈💖🌸
