qed_ptt_release(9)

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

okay so this is qed_ptt_release from the Kernel API Manual, and no cap it's a short one — but it's lowkey important so pay attention 🫶

---

✨ NAME ✨

qed_ptt_release — Release PTT Window. that's it. that's the whole vibe. you're giving the window back 🎀

---

✨ SYNOPSIS ✨

void qed_ptt_release (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt );

literally two args, both pointers, returns nothing. iconic minimalism 💅

---

✨ ARGUMENTS ✨

• p_hwfn — HW device data. the hardware device's whole situation, basically 🌸
• p_ptt — P_ptt. yes, that's the actual description, and honestly? it ate. that's the PTT you're releasing, bestie ✨

---

✨ RETURN ✨

Void. nothing comes back. not a value, not a vibe, not a single crumb 😭 it's giving "no thoughts, head empty" 🦋

---

✨ DESCRIPTION ✨

so here's the tea 🍓 — you should call this at the end of a flow. specifically: at the end of the function that acquired the PTT. like, you took the window, you did your little tasks in it, and now you hand it back. bookend the whole thing, main character energy 👑

do not just wander off and leave the PTT hanging, okay? end of flow = release. periodt 💀
