Dan Carpenter c20ecf7bb6 iommu/sva: Fix signedness bug in iommu_sva_alloc_pasid()
The ida_alloc_range() function returns negative error codes on error.
On success it returns values in the min to max range (inclusive).  It
never returns more then INT_MAX even if "max" is higher.  It never
returns values in the 0 to (min - 1) range.

The bug is that "min" is an unsigned int so negative error codes will
be promoted to high positive values errors treated as success.
