dln2_unregister_event_cb(9)

💅 dln2_unregister_event_cb — the Kernel API Manual glow-up ✨

okay so bestie, we're in the Kernel API Manual today and this one's a lil function called dln2_unregister_event_cb 💖 say it with me: dln2... unregister... event... cb. iconic, we love a descriptive name, no cap 🎀

---

🌸 NAME 🌸

dln2_unregister_event_cb — unregister the callback function for an event

like... it does exactly what it says on the tin, fr fr 🫶

---

✨ SYNOPSIS ✨

void dln2_unregister_event_cb (struct platform_device *pdev , u16 event );

returns nothing (void), takes a struct platform_device * and a u16. short, sweet, to the point 💅

---

🦋 ARGUMENTS 🦋

okay so here's the vibe check on the params:

• pdev — -- undescribed -- 😭 the manpage literally left it blank bestie, not me, i'm just the messenger
• event — also -- undescribed -- 🙈 same situation, the docs said "no thoughts, head empty"

listen, i know we want more, but the source material gives us nothing here and i'm not about to make stuff up. that's not the assignment 💀

---

🔥 DESCRIPTION 🔥

so in the description we finally get a little lore 🌈 and it reads like this, character for character:

• pdev — the sub-device that registered the callback
• event — the event for which to register a callback

that's the whole paragraph, bestie. the manpage said "short king" and meant it 👑 go off i guess 💜

the way this is genuinely the energy of a group chat where someone asks "what does this do" and the reply is just "it does the thing" — but hey, at least it's accurate ✨

🧚 SEE ALSO 🧚

go read these next, i promise they're worth it 🍓:

• Kernel file ./include/linux/mfd/dln2.h
• dln2_transfer(9)
• dln2_transfer_rx(9)
• dln2_transfer_tx(9)

like, the transfer trio is right there waiting for you, main character energy all around ⭐

and that's a wrap, bestie 🎀 this page came to you straight out of ./include/linux/mfd, dated October 2026 — mwah, mwah, drink some water, and go unregister those callbacks responsibly 💖💅🫶
