__platform_register_drivers(9)

✨ __platform_register_drivers(9) ✨

Okay so bestie, this is a page from the Kernel API Manual, and we're about to get into it. Buckle up, because this function is literally the group-chat admin of platform drivers — it adds a whole squad at once. 🫶

---

🌸 NAME 🌸

__platform_register_drivers — register an array of platform drivers

---

🎀 SYNOPSIS 🎀

int __platform_register_drivers (struct platform_driver * const *drivers
, unsigned int count , struct module *owner , const char *mod_name );

---

💅 ARGUMENTS 💅

• drivers — an array of drivers to register. Like, the whole friend group you're adding to the party. 👯‍♀️
• count — the number of drivers to register. Yes, you literally have to tell it how many besties are showing up. ✨
• owner — module owning the drivers. The main character module, iykyk. 👑
• mod_name — module name string. Just a cute little string with the name on it. 🏷️

---

🦋 DESCRIPTION 🦋

Registers platform drivers specified by an array. That's the vibe.

On failure to register a driver, all previously registered drivers will be unregistered — so it's giving "if one of us can't get in, none of us are going in," no cap. 😭 Lowkey iconic loyalty, tbh.

Callers of this API should use platform_unregister_drivers to unregister drivers in the reverse order. Fr fr, reverse order, don't skip that part. 🔄

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure. Simple as that, bestie. 💖

Lowkey a reminder: this page lives at ./drivers/base, dated October 2026, and it's manual page __platform_register_drivers(9). Slay. 💜
