The change is a good one.  If a reviewer (me) sees it then you know the
code's all right and the review effort becomes less - all you need to check
is that the call site is using IS_ERR/PTR_ERR and isn't testing for
NULL.  Less code, less chance for bugs.

Plus it makes kernel text smaller.

Yes, the name is a bit cumbersome.
