free_clk(9)

💅 free_clk(9) — Kernel API Manual

okay bestie, welcome to free_clk(9), a page from the Kernel API Manual. she's short, she's sweet, she's literally four lines of business and one iconic warning. let's get into it 🎀

---

✨ NAME ✨

free_clk — free a clk consumer. that's it. that's the whole job. releasing your lil clock consumer back into the wild 🦋

---

🌸 SYNOPSIS 🌸

void free_clk (struct clk *clk );

no return value, no drama, just vibes and a pointer. ✨

---

🫶 ARGUMENTS 🫶

• clk — the clk consumer you're freeing. yeah. that one. the one you've been holding onto. let her go 💅

---

🔥 DESCRIPTION 🔥

so here's the tea, and you need to hear it: this function assumes the clk has already been unlinked from the clk_core consumer list. like, already done. beforehand. not your problem, not this function's problem. 🙈

bestie, do not skip the unlink step. free_clk is not doing it for you, she is not your cleanup crew, she's just the free-er. the assumption is the whole bit. 😭
