🌸 NAME 🌸

platform_profile_register — creates and registers a platform profile class device. That’s the whole assignment, and it lowkey slays 💅✨

✨ SYNOPSIS ✨

okay so here’s the exact signature, bestie — character-for-character, no cap:

🎀 ARGUMENTS 🎀

• dev — parent device 🫶
• name — name of the class device 🏷️
