You don't need to print error messages for OOM, the mm subsystem will
do.

Thanks for reviewing,  I clone these error messages print from the code
that follows:
   1612         if (!ep->l2t) {
   1613                 pr_err("%s - cannot alloc l2e.\n", __func__);
   1614                 err = -ENOMEM;
   1615                 goto fail4;
   1616         }
