regulator_is_enabled(9)

💖 regulator_is_enabled(9) 💖

okay bestie, welcome to the Kernel API Manual glow-up for regulator_is_enabled(9) — the “is the regulator output enabled” vibe check. it’s giving tiny-but-mighty kernel energy, and we’re obsessed. 🫶✨

---

✨ NAME ✨

regulator_is_enabled — is the regulator output enabled 💅

🌸 SYNOPSIS 🌸

int regulator_is_enabled (struct regulator *regulator );

🎀 ARGUMENTS 🎀

• regulator — regulator source. that’s the one and only argument, bestie. 🎀

🦋 DESCRIPTION 🦋

okay so listen: the device backing this regulator handle can have multiple users. that means it might be enabled even if regulator_enable was never called for this particular source. so don’t come for this function’s wig when another user already turned it on — it’s not lying, it’s just not keeping a private diary for your source only. 😭✨

💅 RETURN 💅

• Positive — the regulator driver backing the source/client has requested that the device be enabled. 💖
• Zero — it hasn’t. 🫶
• Else a negative error number — yep, that’s the error vibe. 💀
