I have no idea where you get that from. The mismatch is printed with:
if (!(new->flags & IRQF_PROBE_SHARED)) {
pr_err("Flags mismatch irq %d. %08x (%s) vs. %08x (%s)\n",
irq, new->flags, new->name, old->flags, old->name);
And its only printed when IRQF_PROBE_SHARED is not set. Your change
would cause printouts where no printouts are due and it'd change the
return value from EBUSY to EINVAL.
Thanks,
