That wasn't my intention.

To be honest this change was a little bit unrelated, which was naughty
of me. I saw:
if ( iommu_intremap ) {
THING A
}
if ( iommu_intremap ) {
THING B
}
and changed it to
if (iommu_intremap ) {
THING A
THING B
}
Is there some subtlety to this code path that I've missed?
Ian.
