iommu/arm-smmu: fix capability checking prior to device attach If somebody attempts to check the capability of an IOMMU domain prior to device attach, then we'll try to dereference a NULL SMMU pointer through the SMMU domain (since we can't determine the actual SMMU instance until we have a device attached). This patch fixes the capability check so that non-global features are reported as being absent when no device is attached to the domain. Signed-off-by: Will Deacon <will.deacon@arm.com>
