tee_device_alloc(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual — this is the page for tee_device_alloc, and it's literally here to allocate a new struct tee_device instance ✨. that's the whole name drop, no cap.

✨ SYNOPSIS ✨

struct tee_device * tee_device_alloc (const struct tee_desc *teedesc ,
       struct device *dev , struct tee_shm_pool *pool , void *driver_data );

🎀 ARGUMENTS 🎀

• teedesc — descriptor for this driver, like the driver's little ID card 💅
• dev — parent device for this device 👑
• pool — shared memory pool, and it's NULL if it's not used 🫶
• driver_data — private driver data for this device, and private means private, bestie 🙈

💖 DESCRIPTION 💖

so this one allocates a new struct tee_device instance ✨. that's the main character move. and when it's time for it to go, the device is removed by tee_device_unregister — that's the removal bestie, don't forget it 🎀.

🌈 RETURN 🌈

you get a pointer to a 'struct tee_device', or an ERR_PTR on failure 💀. not a vibe, but at least it's documented.
