💅 aio_port_set_ch(9) 💅

okay so this is a page from the Kernel API Manual and bestie, it's a short one but it's lowkey important 🎀

✨ NAME ✨

aio_port_set_ch — sets the channels of LPCM, that's literally the whole gig 🦋

---

🌸 SYNOPSIS 🌸

int aio_port_set_ch (struct uniphier_aio_sub *sub );

---

🎀 ARGUMENTS 🎀

• sub — the AIO substream pointer, and hear me out: PCM substream only 👑 like she does not play about non-PCM, okurrr

---

🦋 DESCRIPTION 🦋

So what this does is it sets a suitable slot selecting to the input/output port block of AIO ✨ that's the assignment, that's the vibe, that's the whole function 💅

⚠️ heads up bestie: this function may return an error if it's a non-PCM substream 😭 so like… don't come at her with the wrong substream type, she will simply not

---

⭐ RETURN ⭐

Zero if it ate and everything's successful 💖 otherwise a negative value on error, no cap 🙈
