If we want to play it safe, we should probably introduce something like this to ioport.h: +#define IORESOURCE_IRQ_DEFERRED (1<<6) Then we can populate IRQ resources initially with that. And later on during the driver probe, we know it's safe to populate the resource if res->flags & IORESOURCE_IRQ_DEFERRED. That fixes the $Subject bug, and gets us a little bit further for making more changes later on.
