devm_regulat...supply_alias(9)

💅 devm_regulat...supply_alias(9) — Kernel API Manual, bestie edition 🎀

okay so this one's from the Kernel API Manual, and the function name got cutely truncated to devm_regulat...supply_alias(9) because even man pages have a character limit, slay.

✨ NAME ✨

devm_regulator_register_supply_alias — the resource-managed glow-up of regulator_register_supply_alias(). it's giving "I'll clean up after myself" energy, no cap 💖

🌸 SYNOPSIS 🌸

int devm_regulator_register_supply_alias (struct device *dev , const
       char *id , struct device *alias_dev , const char *alias_id );

that's the whole vibe right there. four args, one int, iconic. 🌈

🦋 ARGUMENTS 🦋

• dev — the device that's getting supplied. like, the one being fed. 🍓
• id — the supply name or regulator ID. yep, it's the identifier bestie.
• alias_dev — the device that should be used to look up the supply. this is the one doing the looking-up, main character energy ✨
• alias_id — the supply name or regulator ID that should be used to look up the supply. so yeah, the lookup-side ID, not to be confused with id, they are literally different things 🙈

💜 DESCRIPTION 💜

okay so the whole point: the supply alias will automatically be unregistered when the source device is unbound. that's the "resource managed" part — you don't have to remember to unregister it yourself, it just handles it. obsessed. 🫶
