💅 regulator_register_supply_alias(9) — the Kernel API Manual glow-up ✨

okay so this is the page for regulator_register_supply_alias(9) from the Kernel API Manual, and bestie it is literally the little matchmaker of the regulator world 🎀 like it's giving "you two should date" but for devices and their power supplies. let's get into it 🦋

🌸 NAME 🌸

regulator_register_supply_alias — Provide device alias for supply lookup 💖

yes that's the whole vibe: it provides an alias so when somebody goes looking for a supply, they find it under a different name. iconic behavior, no cap. 👑

✨ SYNOPSIS ✨

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

four args, one int coming back. the way that signature just sits there 🫶

🎀 ARGUMENTS 🎀

  • dev — the device that will be given as the regulator "consumer". like, this is the one doing the consuming, main character energy fr fr 💅
  • id — the Supply name or regulator ID. this is the name we're aliasing from.
  • alias_dev — the device that should be used to lookup the supply. the one we're pointing at 👀
  • alias_id — the Supply name or regulator ID that should be used to lookup the supply. the other half of the alias, yk?

💜 DESCRIPTION 💜

ok so here's the tea ☕ — all lookups for id on dev will instead be conducted for alias_id on alias_dev.

that's it. that's the whole thing. every single lookup gets redirected, no exceptions, periodt. it's a full-on remap, not a suggestion 🌈

🔥 RETURN 🔥

  • 0 on success 🎉
  • or a negative error number on failure 😭 (ngl, you're gonna wanna check for that one)
