cros_ec_sens...er_push_data(9)

💅 cros_ec_sens...er_push_data(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, we're deep in the Kernel API Manual today and the star of the show is this icon cros_ec_sensorhub_register_push_data 🎀 she's a function, she registers a callback to the hub, and honestly? main character energy. let's get into it 🫶

---

🌸 NAME 🌸

cros_ec_sensorhub_register_push_data — registers the callback to the hub. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

int cros_ec_sensorhub_register_push_data (struct cros_ec_sensorhub
*sensorhub , u8 sensor_num , struct iio_dev *indio_dev ,
cros_ec_sensorhub_push_data_cb_t cb );

like yes bestie we're returning an int, and we're taking four whole parameters. she's thorough 👑

---

🦋 ARGUMENTS 🦋

• sensorhub — the Sensor Hub object itself. ur fave. the whole point 💅
• sensor_num — the sensor that the caller is interested in 👀 lowkey which one we're simping for.
• indio_dev — the iio device to use when a sample arrives. she shows up when the data shows up ✨
• cb — the callback to call when a sample arrives. this is the function we're literally trusting with the news 📣

---

💀 DESCRIPTION 💀

so the callback cb is gonna be used by cros_ec_sensorhub_ring to distribute events from the EC. that's the whole plot. no cap, that's it 🧚

like, cros_ec_sensorhub_ring handles the event distribution era and ur callback is the one catching them. team work makes the dream work, iykyk 🌈

---

🔥 RETURN 🔥

• 0 when callback is registered. slay, we love a clean success 🎉
• EINVAL if the sensor number is invalid or the slot already used. 😭 yeah… that slot's taken bestie, no cap.

ngl bestie, if sensor_num is invalid or that slot is already used, you're getting EINVAL back and there's no negotiating with her 🙈 check ur numbers before u ship, fr fr.
