okay so bestie, welcome to the Kernel API Manual page for irq_domain_remove(9) — yes we are literally in our kernel IRQ domain cleanup era 💅✨

💖 NAME 💖

irq_domain_remove — Remove an irq domain.

✨ SYNOPSIS ✨

void irq_domain_remove (struct irq_domain *domain );

🎀 ARGUMENTS 🎀

• domain — domain to remove. That’s the irq domain you’re saying bye-bye to 👋

🦋 DESCRIPTION 🦋

This routine is used to remove an irq domain. Basically it’s the “okay we’re done here, clean up your room” moment for that domain 😌

⚠️ heads up bestie: the caller must ensure that all mappings within the domain have been disposed of prior to use, depending on the revmap type. no cap, do not skip this part 💀
