pm80xx_chip...rupt_disable(9)

✨ pm80xx_chip_interrupt_disable ✨

okay bestie, so this one lives in the Kernel API Manual and it is exactly what it says on the tin: it disables a PM8001 chip interrupt. that's it. that's the whole vibe. tiny function, big responsibility 🎀

---

🌸 NAME 🌸

pm80xx_chip_interrupt_disable — disable PM8001 chip interrupt 💅

---

🦋 SYNOPSIS 🦋

void pm80xx_chip_interrupt_disable (struct pm8001_hba_info *pm8001_ha ,
u8 vec );

like look at it. two args. returns nothing (void, the little main character who gives nothing back and we respect her for it). ✨

---

💖 ARGUMENTS 💖

• pm8001_ha — our hba card information 🫶 like, this is the actual card's info struct, the whole personality of the hardware in one pointer.
• vec — the interrupt number to disable, as a u8 🔥 so pick your vector, bestie, and this one goes quiet.

ngl the takeaway is just: interrupt goes brrr → silence. you pass the card info and the vector, and that vector stops interrupting. no returns, no drama, periodt. 💅
