ir_do_keyup(9)

💅 ir_do_keyup — the kernel's little "key went up bestie" moment 💖

okay so this page lives in the Kernel API Manual, section 9 — that's the kernel API section, iykyk 🎀

✨ NAME ✨

ir_do_keyup — the internal function that signals a keypress got released 🫶

---

🌸 SYNOPSIS 🌸

void ir_do_keyup (struct rc_dev *dev , bool sync );

like, that's the whole vibe. void, no return, just vibes and side effects 💅

---

🦋 ARGUMENTS 🦋

• dev — the struct rc_dev descriptor of the device. it's giving "which remote are we talking about" energy 👑
• sync — whether or not to call input_sync. yes/no, do it or don't, that's the whole question ✨

---

⭐ DESCRIPTION ⭐

okay so real talk: this function is used internally to release a keypress. and here's the important bit, no cap — it must be called with keylock held. 🔒 like, that's not a suggestion, that's the rule. hold the lock, bestie. don't be the reason things go sideways 😭💀
