void pcibios_penalize_isa_irq (int irq , int active );

🧚 DESCRIPTION 🧚

Okay so this function permits the platform to provide architecture-specific functionality when penalizing ISA IRQs. That's the whole vibe. No cap. 🫶

This is the default implementation. Architecture implementations can override this — main character energy for the arch-specific girlies 👑✨
