Existing drivers (idxd and uacce) only\ncheck the return value with IS_ERR(). This could potentially lead to\na kernel NULL pointer dereference issue if the function returns NULL\ninstead of an error pointer.\n\nIn reality, this doesn't cause any problems because iommu_sva_bind_device()\nonly returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.\nIn this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will\nreturn an error, and the
