Under what circumstances?
This branch is only taken if there's a .create_private_address_space
callback and it only seems to be there on a[67]xx.
a6xx_create_address_space returns:
- an ERR_PTR if msm_iommu_pagetable_create() fails
- retval of msm_gem_address_space_create() otherwise
- retval of msm_iommu_pagetable_create() is nullchecked here
again because we apparently we want to be double sure
- err_ptr(-enomem) is returned if allocating aspace fails
- otherwise aspace is allocated somewhere
