💜 DESCRIPTION 💜

so what does she actually do? this function wraps rpmsg_register_device, and in doing so it prepares the rpdev for use as the basis for the rpmsg chrdev 🔥

basically: rpdev goes in prepped, gets wrapped and set up as the foundation for the rpmsg chrdev, and that's the whole arc. main character energy from start to finish, periodt 👑
