Your commit message says "omit an extra message", which suggests that
there are currently two messages about the memory allocation failure,
and that your patch removes one of them.

If that's the case, it would be nice to know where the other message
is.

If your patch removes the *only* message about the memory allocation
failure, that might be worth doing, but the changelog should be clear
about that and say "I don't think the error message is worthwhile
because the function already returns failure" or something similar.

I don't know what the "Linux allocation failure report" is.

You posted two patches that remove error messages about memory
allocation failures:

  http://lkml.kernel.org/r/dc3922b4-50f6-e7fa-482f-18e6ff5d905f@xxxxxxxxxxxxxxxxxxxxx
  http://lkml.kernel.org/r/fd9d212e-e8da-1aa7-be7f-7bf6d8f1e15f@xxxxxxxxxxxxxxxxxxxxx

These are doing the same thing and could be combined into one patch.
