From e84b7cc457f99ff5d034914e78e1c329df89ebee Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Mon, 8 Oct 2018 10:24:19 +0800 Subject: [PATCH] iommu/amd: Add default branch in amd_iommu_capable() Recent gcc warns about switching on an enumeration, but not having an explicit case statement for all members of the enumeration. To show the compiler this is intentional, we simply add a default case with nothing more than a break statement.
