sca3000_read_ctrl_reg(9)

💅 sca3000_read_ctrl_reg — from the Kernel API Manual, bestie ✨

Okay so bestie, today's main character is sca3000_read_ctrl_reg — a little function straight out of the kernel's Kernel API Manual, and she does exactly one (1) thing but she does it correctly. Let's get into it 🎀

---

🌸 NAME 🌸

sca3000_read_ctrl_reg — read from lock protected control register. That's it, that's the vibe. She reads. She's locked. She's protected. 💅

---

✨ SYNOPSIS ✨

int sca3000_read_ctrl_reg (struct sca3000_state *st , u8 ctrl_reg );

Like, look at her. Two arguments. No notes. 👑

---

🦋 ARGUMENTS 🦋

• st — the driver specific device instance data, aka the whole personality of the device you're working with 🫶
• ctrl_reg — which ctrl register do we want to read. You gotta tell her which one, she's not a mind reader, bestie 🔥

---

💜 DESCRIPTION 💜

Lock must be held. That's the entire description. That's the whole thing. No cap 💀

Fr fr though, do not skip this one — if you're calling this without holding the lock, you are not passing the vibe check. Lock it up first. 🙈
