✨ devm_rtc_device_register(9) ✨

okay bestie, welcome to the Kernel API Manual — this one is about devm_rtc_device_register, and yes it’s giving “managed device” energy but also a lil deprecated, so buckle up 🎀

🌸 NAME 🌸

devm_rtc_device_register — resource managed rtc_device_register()

---

🦋 SYNOPSIS 🦋

struct rtc_device * devm_rtc_device_register (struct device *dev , const
char *name , const struct rtc_class_ops *ops , struct module *owner );

---

💅 ARGUMENTS 💅

• dev — the device to register, like the main character here fr fr
• name — the name of the device (unused) 🙈 yes bestie, it’s literally unused
• ops — the rtc operations structure, the whole vibe of how this thing behaves
• owner — the module owner, gotta give credit where it’s due 👑

---

🫶 DESCRIPTION 🫶

return a struct rtc on success, or an ERR_PTR on error — no cap, that’s the deal ✨

Managed rtc_device_register. The rtc_device returned from this function are automatically freed on driver detach. So like, it cleans up after itself, which is honestly iconic 💖

⚠️ bestie listen: This function is deprecated, use devm_rtc_allocate_device and rtc_register_device instead. like, please don’t make it awkward 😭
