💖 mei_hbm_pg_exit_res(9) — like, the Kernel API Manual page, bestie 💖

Okay so we're in the Kernel API Manual today and the star of the show is mei_hbm_pg_exit_res(9). Buckle up, it's a short one but she's important 🎀

---

✨ NAME ✨

mei_hbm_pg_exit_res — PG exit response received 🦋

Like, that's it. That's the whole vibe. A PG exit response has arrived and this function is the one who answers the door.

---

🌸 SYNOPSIS 🌸

int mei_hbm_pg_exit_res (struct mei_device *dev );

No cap, that's the whole signature. She takes one thing and she gives you back an int. Simple. Iconic. Periodt 💅

---

🎀 ARGUMENTS 🎀

• dev — the device structure. That's the one and only thing you hand her. Just the device struct, bestie, nothing else 💖

---

⭐ RETURN ⭐

• 0 on success 🥳 slay, everything worked
• -EPROTO on state mismatch 😭 the state didn't line up, and she is not subtle about telling you

Heads up: that -EPROTO is literally the "state mismatch" case — don't get surprised when it shows up if your states aren't vibing 🔥
