irq_flags is already used within the same scope, although it's
declared at the top of the function. I'll move the declaration to the
scope where it's used and rename irq_flags -> irq_type, and irq_res ->

You're right. It didn't break the build, which means ioport.h must be
included indirectly. I'll add it back.
