of_changeset_revert(9)

💅 of_changeset_revert — the Kernel API Manual glow-up ✨

okay bestie, welcome to the of_changeset_revert(9) page, straight out of the Kernel API Manual and honestly? it's giving "undo button for the device tree" and we're obsessed 🎀

---

✨ NAME ✨

of_changeset_revert — literally reverts an applied changeset. that's it. that's the vibe. no cap 🫶

---

🌸 SYNOPSIS 🌸

int of_changeset_revert (struct of_changeset *ocs );

---

🦋 ARGUMENTS 🦋

• ocs — the changeset pointer, aka the little handle to the changeset you're about to un-do 💫

---

💖 DESCRIPTION 💖

so here's the tea ☕ — this function reverts a changeset, which means it returns the state of the tree back to what it was before the application. time travel but make it kernel ✨

and bestie, it does not just quietly flip a flag. any side-effects get applied for real, including:

• the creation and destruction of devices 🔥
• the removal of sysfs properties and directories 🗂️

like, the whole clean-up era. main character energy for real 👑

---

⭐ RETURN ⭐

• 0 on success — slay, we ate 💅
• a negative error value in case of an error — not slay, but at least you'll know 😭
