📦 version 7.3.1, in nixpkgs unstable

💖 devm_regulator_get_optional — the Kernel API Manual tea 🫶

okay so bestie, welcome to the devm_regulator_get_optional(9) page ✨ this is a Kernel API Manual moment, and honestly it's giving "small page, big energy" 💅

✨ NAME ✨

devm_regulator_get_optional — the resource-managed glow-up of regulator_get_optional() 🌸

like, same vibe, but the kernel cleans up after you. iconic behavior tbh 👑

🦋 SYNOPSIS 🦋

struct regulator * devm_regulator_get_optional (struct device *dev ,
   const char *id );

yep that's the whole signature, no cap 📝 she takes a device and an id string and hands you back a struct regulator * 🎀

🌈 ARGUMENTS 🌈

  • dev — the device that's getting supplied 🔌 like, who's the consumer here, bestie?
  • id — the supply name or the regulator ID 🏷️ either one, she's flexible

💜 DESCRIPTION 💜

so. it's a managed regulator_get_optional. that's the whole bit 🫶

regulators that come back from this function are automatically regulator_put on driver detach — no manual cleanup era, we love a self-cleaning queen 🧚✨

for more info, go peek at regulator_get_optional — that's where the real lore lives 📖

ngl bestie, regulator_get_optional is the un-managed one, so this page is basically saying "same thing but devm handles the put for you" 💀 don't @ me, that's literally what it says

👑 SEE ALSO 👑

the whole friend group 🫂 and also the kernel file she lives in:

./drivers/regulator/devres.c 📁

like, that is a long list and every single one of them made it in here because we do not skip entries in this house 🎀🔥

and that's the page!! 💖 big sign-off energy: this one lives out of ./drivers/regulator, dated October 2026, and the whole family is filed under devm_regulator_get_optional(9) 🦋 slay, mwah 💅✨
