iommu: Check return of __iommu_attach_device()
Currently iommu_create_device_direct_mappings() is called without checking the return of __iommu_attach_device(). This may result in failures in iommu driver if dev attach returns error. Fixes: ce574c27 ("iommu: Move iommu_group_create_direct_mappings() out of iommu_group_add_device()") Signed-off-by:Shameer Kolothum <shameerali.kolothum.thodi@huawei.com> Link: https://lore.kernel.org/r/20201119165846.34180-1-shameerali.kolothum.thodi@huawei.comSigned-off-by:
