pm80xx_chip_isr(9)

💅 pm80xx_chip_isr(9) — kernel API manual, but make it make sense

okay so bestie, welcome to the pm80xx_chip_isr page 🎀 this one is short and sweet — it's literally section 9 of the kernel API manual, and it's about the PM8001's ISR handler. yes, that ISR handler. the one that gets called when the card has ✨something to say✨. buckle up, it's only two arguments deep and we're done 🦋

---

✨ NAME ✨

pm80xx_chip_isr — the PM8001 isr handler, periodt 🔥

---

🌸 SYNOPSIS 🌸

irqreturn_t pm80xx_chip_isr (struct pm8001_hba_info *pm8001_ha , u8 vec);

like, that's the whole signature. she's compact. she's iconic. she takes two things and returns an irqreturn_t 👑

---

💖 ARGUMENTS 💖

• pm8001_ha — our hba card information 💳 hi bestie, this is the actual card we're talking about, all its little details bundled up in one struct.
• vec — the irq number 🔢 literally the irq number, that's it, that's the whole vibe check.
