💅 mpc52xx_irqhost_map(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the <pink>Kernel API Manual</pink> ✨ and lemme tell you about mpc52xx_irqhost_map — it's the hook that maps from a virq to an irq_chip structure. that's the whole vibe. she's a connector, a matchmaker, a little function with main character energy 🎀

🌸 NAME 🌸

mpc52xx_irqhost_map — Hook to map from virq to an irq_chip structure 🫶

✨ SYNOPSIS ✨

int mpc52xx_irqhost_map (struct irq_domain *h , unsigned int virq ,
       irq_hw_number_t irq );

like, that's her signature. no cap, that's exactly how you call her 💖

🦋 ARGUMENTS 🦋

so about the args… ngl, the docs are giving absolutely nothing here 🙈 the original literally says -- undescribed -- for all three, and I'm not gonna make stuff up because that would be lying to you, bestie:

• h — -- undescribed -- 😭
• virq — -- undescribed -- 😭
• irq — -- undescribed -- 😭

fr fr, that's all the source gives us. three mystery parameters, zero lore. iconic of them, honestly 💀
