Why did you not reply directly with this request for the update steps
with the subject "Delete an error message for a failed memory allocation
in tpm_...()"?

I find that there can be difficulty to show an appropriate information
source for the reasonable explanation of this change pattern.

Shouldn't this information source for the explanation be the submitter?

I offered a bit of information. I agree that it could become better eventually.

I'd hope they understand what it is they are submitting.

I do this to some degree.   ;-)

But I would appreciate if I could refer to a single Linux document
for this change pattern around questionable error messages.
Would a corresponding link for an accepted explanation in the documentation
be nice in this case?
