commit 6cf18e6927 upstream.
This interrupt handler is broken in several ways:
- It loops forever when the op code is not decodeable
- It never returns IRQ_HANDLED because the only way to exit the loop
returns IRQ_NONE unconditionally.
The whole concept of this is broken. Creating devices in an interrupt
handler is beyond any point of sanity.
Make it at least behave halfways sane so accidental users do not have to
deal with a hard to debug lockup.
