snd_hdac_ext...wer_down_all(9)

💤 snd_hdac_ext_bus_link_power_down_all — a Kernel API Manual moment 💤

Okay bestie, so this one's from the Kernel API Manual, and the star of the show is snd_hdac_ext_bus_link_power_down_all. The whole entire name got chopped in the header because it's lowkey too long, but you know her 🫶.

✨ NAME ✨

snd_hdac_ext_bus_link_power_down_all — power down all hda link 🔌💤

Like, all of them. Every single link. Lights out, bestie 🌙.

🎀 SYNOPSIS 🎀

int snd_hdac_ext_bus_link_power_down_all (struct hdac_bus *bus );

It returns an int, she takes exactly one arg, and no, we are not adding a second one, that's not the vibe 💅.

🌸 ARGUMENTS 🌸

• bus — the pointer to the HDAC bus object 🚌✨ That's it. That's the whole parameter list. One bus, pointing at your HDAC bus object. Iconic, honestly.
