scmi_bind_event_handler(9)

💅 scmi_bind_event_handler — like, the Kernel API Manual era 🎀

okay so bestie, welcome to scmi_bind_event_handler(9), a little helper from the SCMI notification corner of the kernel that is genuinely doing the most for you rn 💖

✨ NAME ✨

scmi_bind_event_handler — a helper that will literally try to bind a handler to an event 🫶

✨ SYNOPSIS ✨

int scmi_bind_event_handler (struct scmi_notify_instance *ni , struct
                              scmi_event_handler *hndl );

✨ ARGUMENTS ✨

• ni — a reference to the notification instance you're gonna use 🌸
• hndl — the event handler that's about to get bound, no cap 👑

✨ DESCRIPTION ✨

So here's the vibe check: if an associated registered event is found, this function moves the handler out of the pending table and into the registered table. That's it, that's the whole glow-up ✨ it's giving promotion arc, honestly 🦋

✨ CONTEXT ✨

⚠️ bestie read this one: this function assumes it's being called with pending_mtx already acquired 🔒 like, do not come in here without the lock, that's not the move 💀

✨ RETURN ✨

• 0 on success 🎉 that's the win, slay 💅
