💅 mei_hdcp_close_session(9) — like, the Kernel API Manual, bestie

okay so welcome to mei_hdcp_close_session, straight out of the Kernel API Manual ✨ this one is a <hotpink>9</hotpink>-section page (kernel internals, iykyk) and it's basically the "log out" button for an HDCP session. short page, but every word slays. let's go 🎀

---

✨ NAME ✨

mei_hdcp_close_session — close the Wired HDCP Tx session of ME FW per port. it also disables the authenticated state of the port. like, it doesn't just leave the session hanging, it properly shuts the whole vibe down 🙈

---

🌸 SYNOPSIS 🌸

int mei_hdcp_close_session (struct device *dev , struct hdcp_port_data *data );

---

🦋 ARGUMENTS 🦋

• dev — the device corresponding to the mei_cl_device. it's giving "who am i doing this for" energy 💖
• data — Intel HW specific hdcp data. no cap, it's hardware-specific so don't go improvising 🫶

---

⭐ RETURN ⭐

• 0 on Success 👑
• <0 on Failure 💀 (yeah, negative numbers mean bad news, that's just how it is)

fr fr, check that return value. <0 is not a vibe, it's a failure, and you should absolutely care about it 😭
