Under some circumstances it might be required to return NULL from the create_address_space callback, meaning that the driver should use global address space. Use IS_ERR_OR_NULL() to guard aspace->pid assignment instead of just IS_ERR(). This plays well with the IS_ERR_OR_NULL() check few lines below.
