Using new API dmaengine_prep_config_sg() to simple code. dmaengine_prep_config_sg() does not distinguish between configuration failures and descriptor preparation failures, as both are reported through a NULL return value. Converting both cases to -ENOMEM is therefore acceptable and consistent with the helper's abstraction. In practice, most users only care whether the operation succeeds or fails, and do not depend on the exact errno value returned from this path.
