devm_clk_put(9)

💅 devm_clk_put(9)

okay bestie, so this page lives in the Kernel API Manual and it's all about letting go of a clock the ~managed~ way. releasing your grip, but make it devres. 🫶

---

✨ NAME ✨

devm_clk_put — "free" a managed clock source. that's it, that's the whole vibe. it's your official clock-drop. 🎀

---

🎀 SYNOPSIS 🎀

void devm_clk_put (struct device *dev , struct clk *clk );

literally the entire function signature, no surprises, no plot twist. 💅

---

🦋 ARGUMENTS 🦋

• dev — the device you used to acquire the clock. it's the whole reason this is a managed clock, so don't forget who got you here. 🧚
• clk — the clock source itself, and not just any clock: the one you got with devm_clk_get. 💖

---

💀 NOTE 💀

drivers must ensure that all clk_enable calls made on this clock source are balanced by clk_disable calls prior to calling this function. unbalanced enables? that's a no from the kernel, fr fr. 🔥

clk_put should not be called from within interrupt context. nope, not in an IRQ, not in your interrupt-era. 🙈

🌸 k thx bye 🌸

this little page came to you straight from ./include/linux and it's dated October 2026 — so yeah, future-coded and iconic. go balance those enables and stay out of interrupt context, bestie. slay 💅✨🎀
