int mei_hbm_pg_enter_res (struct mei_device *dev );

that's it. one function, one signature, zero drama (well… kinda, see RETURN 👀).

🦋 ARGUMENTS 🦋

• dev — the device structure. the main character of this whole operation, no cap. everything happens through her. 👑

⭐ RETURN ⭐

• 0 — slay! success. everything went off without a hitch ✨
• -EPROTO — oof, state mismatch 😭 the states did not match, and that's on protocol, fr fr.
