It looks like @info is not initialized except for info::fwspec. That's a
patently bad idea.

Why has fwspec to be in info in the first place? What's wrong with doing
the obvious:

int irq_populate_fwspec_info(struct irq_fwspec *fwspec, struct irq_fwspec_info *info)
{
        memset(info, 0, sizeof(info));

        ....

No?

Thanks,
