clk_bulk_unprepare(9)

💅 clk_bulk_unprepare 💅

okay bestie, welcome to the Kernel API Manual — yes it's a real manual, yes it's the kernel, yes we're gonna make it slay. today's main character is clk_bulk_unprepare, and she's literally the undo button for a whole squad of clock sources. 🎀

---

✨ SYNOPSIS ✨

void clk_bulk_unprepare (int num_clks , const struct clk_bulk_data *clks );

that's it, that's the whole signature. she takes two things and returns absolutely nothing (void, iconic, no drama). 🫶

---

🌸 ARGUMENTS 🌸

• num_clks — the number of clk_bulk_data in the crew. basically how many besties are in the group chat. 💖
• clks — the clk_bulk_data table being unprepared. that's the actual list, and no cap, she's about to un-prep all of them. 🦋

---

💜 DESCRIPTION 💜

so here's the vibe check: clk_bulk_unprepare may sleep. which is like... the whole thing that differentiates it from clk_bulk_disable. 😴✨ not the same function, not the same energy, do not confuse them.

and about the return? she returns 0 on success, and -EERROR otherwise. that's the whole tea. 🍓

lowkey important, bestie: the sleeping thing is not a cute personality trait, it's a real technical caveat. if you're somewhere you can't sleep, that's a you problem and it's giving undefined chaos. 🙈
