Subject: [PATCH 17/18] iommu/vt-d: Remove duplicated check in intel_svm_bind_mm()
Date: Sat, 16 May 2020 14:21:00 +0800	[thread overview]
Message-ID: <20200516062101.29541-18-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20200516062101.29541-1-baolu.lu@linux.intel.com>

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