dfll_unregister_clk(9)

💖 NAME 💖

Okay bestie, this is the dfll_unregister_clk(9) page from the Kernel API Manual — and it does exactly one iconic little job: it unregisters the DFLL output clock. No cap.

---

🎀 SYNOPSIS 🎀

void dfll_unregister_clk (struct tegra_dfll *td );

---

🌸 ARGUMENTS 🌸

• td — the DFLL instance. That's the one you're passing in, bestie. 🫶

---

🦋 DESCRIPTION 🦋

So here's the whole vibe: dfll_unregister_clk unregisters the DFLL's output clock from the Linux clock framework and from clkdev. That's it. That's the task. Slay. ✨

It has no return value. Literally nothing comes back — the signature is void, so don't be standing there waiting for a result, queen. 💅

No return value, bestie. Not a thing. Not even a little one. 😭
