Subject: iommu/vt-d: Remove duplicated check in intel_svm_bind_mm()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7482fd59259a7f23e191c14b8a126a0f6981b3e4;p=linux.git

iommu/vt-d: Remove duplicated check in intel_svm_bind_mm()

The info and info->pasid_support have already been checked in previous
intel_iommu_enable_pasid() call. No need to check again.
