Subject: vfio-pci: Use uintptr_t for void* cast
X-Git-Tag: v1.3.0-rc0~300^2~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5976cdd58b657692e8c1af5310d55a60aecc9089;p=thirdparty%2Fqemu.git

vfio-pci: Use uintptr_t for void* cast

We don't seem to run into any sign extension problems, but
unsigned looks more correct.
