iommu/amd: remove compiler warning due to IOMMU_CAP_NOEXEC
Some versions of GCC get unduly upset when confronted with a switch that doesn't explicitly handle all cases of an enum, despite having an implicit default case following the actualy switch statement: drivers/iommu/amd_iommu.c: In function 'amd_iommu_capable': >> drivers/iommu/amd_iommu.c:3409:2: warning: enumeration value 'IOMMU_CAP_NOEXEC' not handled in switch [-Wswitch] switch (cap) { This patch adds a case for IOMMU_CAP_NOEXEC to the amd IOMMU driver to remove this warning. Cc: Joerg Roedel <jroedel@suse.de> Signed-off-by: Will Deacon <will.deacon@arm.com>
