🌸 cmd64x_sff_irq_clear — like, the kernel API manual page, bestie 🌸

okay so real talk, this one lives in the Kernel API Manual (section 9, iykyk) and it's called cmd64x_sff_irq_clear. it's short, it's sweet, it's giving "tiny function, big responsibility" energy 💅

ngl there's no scary warning here, but like — it's a register-clearing function in the kernel, so maybe don't call it from your random userspace program, bestie 😭
