🌸 NAME 🌸

tsi721_dbell_handler — the Tsi721 doorbell interrupt handler, aka the girl who answers the door every single time 🔔💅

✨ SYNOPSIS ✨

int tsi721_dbell_handler (struct tsi721_device *priv );

like, that's the whole signature. that's her. no cap.

🦋 ARGUMENTS 🦋

  • priv — the tsi721 device-specific data structure. literally the device's whole personality in one struct, she needs it to do her thing 🫶

👑 DESCRIPTION 👑

so what does she actually do? bestie, she handles inbound doorbell interrupts. 🔔✨

here's the tea: she copies the doorbell entry from an internal buffer into the DB message FIFO, and then she schedules a deferred routine to process the queued DBs. like, she doesn't do everything herself — she's a delegator, she's got main character energy but she knows how to share the spotlight. 💅

🌈 RETURN 🌈

0

that's it. that's the return value. zero. iconic, honestly. ⭐
