[PATCH] intel_iommu: Fix shadow local variables on "size" |
Date: |
Fri, 22 Sep 2023 12:04:10 -0400 |
This patch fixes the warning of shadowed local variable:
../hw/i386/intel_iommu.c: In function ‘vtd_address_space_unmap’:
../hw/i386/intel_iommu.c:3773:18: warning: declaration of ‘size’ shadows a
previous local [-Wshadow=compatible-local]
3773 | uint64_t size = mask + 1;
| ^~~~
../hw/i386/intel_iommu.c:3747:12: note: shadowed declaration is here
3747 | hwaddr size, remain;
| ^~~~
