regulator_unlock(9)

✨ NAME ✨

okay so welcome to regulator_unlock(9), straight out of the Kernel API Manual, and this page is here to do one (1) thing and then leave: unlock a single regulator. that's the name, that's the vibe, we love a focused icon 💅

🌸 SYNOPSIS 🌸

void regulator_unlock (struct regulator_dev *rdev );

🎀 ARGUMENTS 🎀

• rdev — regulator_source. that's the regulator source bestie getting passed in; the page gives us exactly that and no extra lore, so we're not inventing any 🫶

💖 DESCRIPTION 💖

bestie, the whole plot is literally this: this function unlocks the mutex when the reference counter reaches 0. that's the entire behavior. reference counter hits 0? boom, mutex unlocked. it's giving precise, it's giving tiny, it's giving exactly what it says ✨

no cap: “when the reference counter reaches 0” is the whole condition here. keep that in your notes 😌
