mhi_notify(9)

✨ mhi_notify(9) ✨

okay so this is mhi_notify, straight out of the Kernel API Manual, section 9, and it's literally the function that tells your MHI client driver "hey bestie, here's the tea on your client device's status" 👀💅

---

🌸 NAME 🌸

mhi_notify — notify the MHI client driver about client device status 💖

---

🎀 SYNOPSIS 🎀

void mhi_notify (struct mhi_device *mhi_dev , enum mhi_callback cb_reason );

that's it. that's the whole thing. returns void, so like, no receipts, no return value, she just does her thing and leaves 🦋

---

💜 ARGUMENTS 💜

• mhi_dev — the MHI device instance, aka the main character of this whole operation 👑
• cb_reason — the MHI callback reason, aka why we're all gathered here today 🎀
