okay so this is from the Kernel API Manual, bestie — and it’s giving “resource-managed device registration” energy ✨

✨ SYNOPSIS ✨

struct lcd_device * devm_lcd_device_register (struct device *dev , const
       char *name , struct device *parent , void *devdata , const struct
       lcd_ops *ops );

---

✨ ARGUMENTS ✨

• dev — the device to register 🫶
• name — the name of the device 🎀
• parent — a pointer to the parent device 🌸
• devdata — an optional pointer to be stored for private driver use 👑
• ops — the lcd operations structure 💜

✨ DESCRIPTION ✨

This returns a struct lcd on success, or an ERR_PTR on error 😭
