From: Mark Rustad <mark.d.rustad@intel.com>

Resolve a shadow warning produced in a W=2 build by changing
the name of a local variable from s32 to ds32. Since s32 clashes
with the well-known typedef, any macro expansion that could
someday be used that might attempt to use an s32 type would fail
to compile. It is best to eliminate the hazard.
