okay bestie, welcome to the Kernel API Manual — this one's a lil function called snd_ac97_read, and honestly? she's iconic in the most lowkey way. let's get into it ✨

🌸 NAME 🌸

snd_ac97_read — read a value from the given register. that's it. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

unsigned short snd_ac97_read (struct snd_ac97 *ac97 , unsigned short reg );

---

🎀 ARGUMENTS 🎀

• ac97 — the ac97 instance. like, the whole AC'97 codec situation you're working with. the main character, if you will 👑
• reg — the register to read. you're telling her which register you wanna peek at, and she will go get it for you 🫶

---

💜 DESCRIPTION 💜

so basically: reads a value from the given register. no cap. 💀

and here's the tea — it invokes the read callback directly after the register check. so the order is: register check first, then the read callback gets called straight away. no detours, no extra steps, she just goes ✨

---

🌈 RETURN 🌈

the read value. that's the answer. that's what you get back. periodt. 💖
