Subject: KVM: Fix order passed to iommu_unmap
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=90a49e22c05e1c5035943a293c7758c7999d8a76;p=users%2Fdwmw2%2Flinux.git

KVM: Fix order passed to iommu_unmap

This is obviously a left-over from the the old interface taking the
size. Apparently a mostly harmless issue with the current iommu_unmap
implementation.
