💅 snd_usb_endpoint_implicit_feedback_sink (9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil function from the sound/usb corner of the kernel and it's genuinely so straightforward you're gonna slay it. no cap.

🌸 NAME 🌸

snd_usb_endpoint_implicit_feedback_sink — literally just reports the endpoint usage type 🎀

---

✨ SYNOPSIS ✨

int snd_usb_endpoint_implicit_feedback_sink (struct snd_usb_endpoint *ep
);

like. that's it. that's the whole call. one argument, one int back. iconic behavior honestly 🫶

🦋 ARGUMENTS 🦋

• ep — the struct snd_usb_endpoint in question 👑 bestie is literally the star of the show here, we're asking about this endpoint.

💖 DESCRIPTION 💖

so what does it actually do? it determines whether an endpoint is driven by an implicit feedback data endpoint source 🧚

that's the vibe check. you hand it an endpoint, it tells you if that endpoint's being driven by an implicit feedback data endpoint source. yes/no energy, no drama, no side quests 💀
