💖 zl3073x_write_u16 — like, the 16-bit register writer bestie 💖

okay so this is a Kernel API Manual page for zl3073x_write_u16(9) — yes that's a function, yes it's in the kernel, yes you're gonna understand it, periodt. 🎀

---

✨ SYNOPSIS ✨

int zl3073x_write_u16 (struct zl3073x_dev *zldev , unsigned int reg ,
       u16 val );

that's the whole signature, no cap. three args, one int back. 💅

---

🌸 ARGUMENTS 🌸

• zldev — your zl3073x device pointer, like the little handle to the actual chip bestie 🫶
• reg — the register you're writing to, an unsigned int, iykyk
• val — the value you're writing in there, a u16, so a 16-bit baby 🍓

---

🦋 DESCRIPTION 🦋

so the whole vibe is: it writes your value into the given 16bit register. that's it. that's the function. it takes val and it puts it into reg on zldev. iconic, minimal, main character energy honestly ✨

⭐ RETURN ⭐

• 0 — slay, it worked, success 💖
• <0 — nope, error, something went wrong, not the vibe 😭
