wmi_remove_notify_handler(9) 💅

okay so bestie, this is the Kernel API Manual page for wmi_remove_notify_handler(9), and it is deprecated — not me serving outdated energy, that's literally what the page says 😭. We're unregistering a handler for WMI events, and I'm gonna keep every detail intact, periodt.

🌸 NAME 🌸

wmi_remove_notify_handler — Unregister handler for WMI events (deprecated)

okay so that's the whole name situation: unregister that WMI event handler, and remember it's deprecated, bestie 💀.

✨ SYNOPSIS ✨

acpi_status wmi_remove_notify_handler (const char *guid );

🎀 ARGUMENTS 🎀

• guid — a 36 char string of the form fa50ff2b-f2e8-45de-83fa-65417f2f49ba 🫶

🦋 DESCRIPTION 🦋

This one unregisters the handler for events sent to the ACPI-WMI mapper device. That's the entire assignment, no cap. It's not giving "new and fresh" energy though — the NAME section already spilled that this thing is deprecated 💅.

👑 RETURN 👑

It returns acpi_status, signaling success or error. So like, you get a little status moment that says whether it slayed or flopped 😭.
