💅 mei_cl_device_match(9) — a Kernel API Manual moment 🎀

okay bestie, sit down, because we're diving into the Kernel API Manual today and honestly? This one's a little cutie. It's mei_cl_device_match — the device match function. That's it. That's the whole NAME. Short, sweet, iconic. ✨

---

🌸 SYNOPSIS 🌸

int mei_cl_device_match (struct device *dev , const struct device_driver
*drv );

like, literally just hand it a device and a driver and it does its lil matchmaking thing 🫶

---

🦋 ARGUMENTS 🦋

• dev — the device. yeah. just... the device. main character of the pairing 💖
• drv — the driver. the other half of the situationship. we're checking if these two are a match 💅

---

⭐ RETURN ⭐

• 1 — slay! a matching device was found 👑
• 0 — nope, no match. not every vibe check passes, and that's okay 😭
