__mhi_ep_driver_register(9)

🎀 __mhi_ep_driver_register (9) 🎀

okay so bestie, we're in the Kernel API Manual today and this one is genuinely so straightforward you're gonna slay it. It's the function that introduces your driver to the MHI Endpoint bus — like, the official "hey everyone, this one's with me" moment. 💅

✨ NAME ✨

__mhi_ep_driver_register — the one that registers a driver with the MHI Endpoint bus. that's it, that's the vibe. 🦋

🌸 SYNOPSIS 🌸

int __mhi_ep_driver_register (struct mhi_ep_driver *mhi_drv , struct
module *owner );

look at her. two params, one int coming back. main character energy fr fr. ✨

💖 ARGUMENTS 💖

• mhi_drv — the driver that's gonna get associated with the device. like, this is the driver in question, the one being introduced to the bus. 🫶
• owner — the module owner. classic module bookkeeping, you know the drill. 👑

⭐ RETURN ⭐

0 if the driver registration succeeds — queen behaviour, we love a zero. 💚

otherwise you get a negative error code, which is the kernel's way of being like "hm, no 💀". check it, don't ignore it. iykyk.

🦋 SEE ALSO 🦋
