I'm sorry, but this is getting extremely confusing. Can you please supply
a complete kernel log, where also other potentially relevant messages
would be present (like those issued when PHYSDEVOP_setup_gsi has failed,
as ought to happen when invoked the 2nd time for the same GSI)? It's fine
if you want to leave your extra printk()s in place for this, but please
be sure (perhaps by way of also supplying the patch you use) to make clear
where exactly they live, so we can make sense of those extra log messages.
