🎀 NAME 🎀

tsi721_pw_handler — Tsi721 inbound port-write interrupt handler

🦋 SYNOPSIS 🦋

int tsi721_pw_handler (struct tsi721_device *priv );

🌸 ARGUMENTS 🌸

• priv — the tsi721 device private structure. that's it, that's the whole argument list, she's low maintenance 🫶

💖 DESCRIPTION 💖

okay so picture this: this function handles inbound port-write interrupts. that's its whole main character job ✨

what it actually does, step by step, no cap:

• copies the PW message from an internal buffer into the PW message FIFO 📥
• schedules a deferred routine to process the queued messages 🔥

so it's giving "short and sweet on the surface, but quietly setting up the real work for later" — honestly iconic.

⭐ RETURN ⭐

returns 0. that's it. zero. the number. slay 💀
