✨ n_hdlc_tty_wakeup ✨

okay so bestie, welcome to the kernel API manual — this one's a lil function from the n_hdlc corner of the universe, and honestly? she's short but she's important 💅

n_hdlc_tty_wakeup — the callback for transmit wakeup, aka the "hey girl, I can take more data now" signal 🫶

---

🦋 SYNOPSIS 🦋

void n_hdlc_tty_wakeup (struct tty_struct *tty );

like, that's the whole signature. clean. minimal. iconic. ✨

---

💖 DESCRIPTION 💖

okay so the vibe here is: this one gets called when the low level device driver can accept more send data. that's it. that's the whole job. she's basically the group chat notification that says "we're open for business again" 📥✨
