clk_hw_get_of_node(9)

💅 clk_hw_get_of_node (9) — the Kernel API Manual, bestie edition ✨

okay so you're looking at the clk_hw_get_of_node(9) page from the Kernel API Manual, and honestly? it's a short one. like, grab a lil snack, this is a quick read 🍓

---

🌸 NAME 🌸

clk_hw_get_of_node — get device_node from a hardware clock. that's the whole gig. no cap.

---

🎀 SYNOPSIS 🎀

struct device_node * clk_hw_get_of_node (const struct clk_hw *hw );

literally just hand it a clk_hw pointer and it hands you back a struct device_node *. iconic behavior tbh 🫶

---

🦋 ARGUMENTS 🦋

• hw — the clk_hw pointer you're pulling the struct device_node from. that's it, that's the only thing it wants from you 💜

---

✨ DESCRIPTION ✨

so this is a little helper function whose entire main character energy is: get the struct device_node that's associated with a hardware clock. it's giving "small function, very clear purpose" 💅 no drama, no side quests.

---

⭐ RETURN ⭐

it returns the struct device_node associated with the clock. and if there literally isn't one? you get NULL. like, no node, no vibes. NULL. periodt 🙈

don't forget the NULL case exists — check before you go dereferencing, bestie, fr fr 😭
