💖 mei_cl_bus_dev_init(9) 💖

okay bestie, buckle up — this one's from the Kernel API Manual, and it's honestly kind of a glow-up moment for mei client devices. let's get into it 🫶

---

✨ NAME ✨

mei_cl_bus_dev_init — allocates and initializes an mei client device, and it does it based on an me client. that's the whole vibe. it's giving "build-a-bear but for kernel devices" 🧸

---

🌸 SYNOPSIS 🌸

void mei_cl_bus_dev_init (struct mei_device *bus , struct mei_me_client *me_cl );

no cap, that's the whole signature — it returns void, so don't go looking for a return value, there isn't one 💅

---

🎀 ARGUMENTS 🎀

• bus — the mei device. that's your main character right there 👑
• me_cl — the me client. the little sidekick it's building the device from 🦋

---

💜 DESCRIPTION 💜

Locking: this gets called under the "dev->cl_bus_lock" lock.

literally do not forget that lock, bestie 😭 it's right there in the description for a reason — this function expects to already be running under "dev->cl_bus_lock" and that's the entire description. short and iconic. periodt.
