regulator_register_notifier(9)

Hey bestie 💖 this is the regulator_register_notifier(9) page from the Kernel API Manual. Buckle up, it's short but cute.

💖 NAME 💖

regulator_register_notifier — register regulator event notifier ✨

✨ SYNOPSIS ✨

int regulator_register_notifier (struct regulator *regulator , struct
notifier_block *nb );

🎀 ARGUMENTS 🎀

• regulator — the regulator source, literally the regulator source you're giving it. 💅
• nb — the notifier block that's getting registered. 🫶

🌸 DESCRIPTION 🌸

Okay so the actual move is register that notifier block so it can receive regulator events. That's the whole plot. Register notifier block to receive regulator events. Periodt. 💖

🦋 RETURN 🦋

• 0 — success, slay, iconic, we love to see it. ✨
• a negative error number — failure, bestie, and it's giving "something went wrong." 😭
