💅 zpa2326_poll_oneshot_completion — Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual entry for zpa2326_poll_oneshot_completion, and honestly? this one is a little gremlin of a function and i love her for it 🫶

---

🌸 NAME 🌸

zpa2326_poll_oneshot_completion — the "actively poll for one shot data ready" girlie 💅

like, she doesn't wait for a knock on the door. she keeps checking. iconic, slightly unhinged, deeply necessary.

---

✨ SYNOPSIS ✨

int zpa2326_poll_oneshot_completion (const struct iio_dev *indio_dev );

that's the whole vibe. one arg, returns an int. clean. no cap.

---

🎀 ARGUMENTS 🎀

• indio_dev — the IIO device that's all tangled up with the sampling hardware 💖 it's the <italic>const struct iio_dev *</italic> up there in the synopsis, and she's the main character of this whole operation.

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function literally loops over registers content to detect the end of the sampling cycle. she's out here reading the registers over and over, checking, checking, checking, like a bestie refreshing the group chat waiting for someone to reply 😭

and the reason she exists? it's the fallback. this is the move you pull when DT declared no valid interrupt lines — i.e. no one set up an interrupt to politely tap her on the shoulder, so she just goes and looks herself. self-sufficient queen energy 👑

iykyk: no interrupt? no problem. she polls.

---

🔥 RETURN 🔥

• Zero when it all goes right — slay ✨
• a negative error code otherwise — not slay 💀

🫶 reminder bestie: if there IS a valid interrupt line declared in DT, you probably don't need to be here manually polling. this one's the backup plan, not the first choice. periodt.
