🎀 SYNOPSIS 🎀

int snd_hdac_ext_bus_link_power_up_all (struct hdac_bus *bus );

That's it. That's the whole vibe check. It returns an int, it takes one pointer, and it is literally not that deep. 💅

✨ ARGUMENTS ✨

• bus — the pointer to HDAC bus object 👑 like, the one singular thing you gotta hand over. It is the pointer to the HDAC bus object. Give it the bus, it turns the links on. Iconic behavior, honestly.
