💜 irq_find_matching_fwspec(9) 💜

okay so welcome to the Kernel API Manual, bestie — this one's all about irq_find_matching_fwspec, and it's honestly kind of a vibe 🦋

✨ NAME ✨

irq_find_matching_fwspec — literally locates a domain for a given fwspec 💅

🌸 SYNOPSIS 🌸

struct irq_domain * irq_find_matching_fwspec (struct irq_fwspec *fwspec
, enum irq_domain_bus_token bus_token );

🎀 ARGUMENTS 🎀

• fwspec — the FW specifier for an interrupt 🧚 that's the little description of the interrupt you're rolling in with
• bus_token — domain-specific data ✨ yep, that's the whole description, it's giving "mysterious but make it kernel"
