regulator_bu...supply_alias(9)

💅 regulator_bulk_register_supply_alias — register multiple aliases, bestie

okay so this page is from the Kernel API Manual, and the function name got a little truncated in the header (regulator_bu...supply_alias(9)) but like, we know who she is. it's giving "long name, big responsibility" ✨

---

🌸 SYNOPSIS 🌸

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

literally the whole signature, character for character, no cap 🫶

---

🎀 ARGUMENTS 🎀

• dev — the device that's gonna be handed the regulator "consumer" role. main character energy fr.
• id — a List of supply names or regulator IDs. plural vibes.
• alias_dev — the device that should actually be used to look up the supply 👀
• alias_id — a List of supply names or regulator IDs that should be used to look up the supply
• num_id — how many aliases we're registering. the count. the quantity. the amount. 💅

---

✨ DESCRIPTION ✨

so this helper function is the ultimate group-project glitch: it lets drivers register several supply aliases in one operation. one shot, all the aliases. iconic 🦋

but here's the tea — if any of the aliases can't be registered, then any aliases that were already registered get removed before it returns to the caller. it's a full rollback, bestie, no half-finished situationship allowed. 😭

---

🌈 RETURN 🌈

0 on success, or a negative error number on failure. that's it. that's the whole vibe check ⭐

and that's a wrap, bestie!! this cutie lives in ./drivers/regulator and the page is dated October 2026. go forth and register your aliases responsibly 🧚‍♀️🎀💖
