So Andy is correct in that we try to avoid shadowing error codes where possible.
I accepted v1 of this series because it fixed an existing problem in a way
consistent with the existing code.

Since v1 is already in for-next, let's consider the following a subsequent
cleanup. Would you please create a new patch to address the shadowing error code
issues on top of the v1 patch series.
