From c79c09ad31e2c0a5ba0166b284f433b95d9c4c18 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 5 Apr 2022 13:25:11 +0100 Subject: [PATCH] crypto: qat - stop using iommu_present() Even if an IOMMU might be present for some PCI segment in the system, that doesn't necessarily mean it provides translation for the device we care about. Replace iommu_present() with a more appropriate check.
