💅 mpt_event_deregister — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and the main character is mpt_event_deregister(9) 🎀

✨ NAME ✨

mpt_event_deregister — literally the "unsubscribe" button for your protocol-specific event callback handler 🦋

🌸 SYNOPSIS 🌸

void mpt_event_deregister (u8 cb_idx );

💖 ARGUMENTS 💖

  • cb_idx — the callback handle you got when you registered before. yeah, that one. the previously-registered one 👑

🫶 DESCRIPTION 🫶

so here's the vibe: every protocol-specific driver should call this routine when it doesn't handle events (or can no longer handle events), or when its module is getting unloaded 🌈

basically: when your driver's event era is over, you call this and you log off gracefully. no lingering callbacks, no awkward "why is my handler still firing" energy 💀

👑 SEE ALSO 👑

Kernel file ./drivers/message/fusion/mptbase.c — and honestly the whole friend group showed up, so let's give them their moment ✨

and that's the whole page, bestie, we ate and left absolutely no crumbs 🍓

sign-off szn: this little icon lives at ./drivers/message/fusion, dated October 2026, and it's mpt_event_deregister(9) all the way down. mwah 💋💜
