My mistake, I wrote the guilty patch
uevent-improve-error-checking-and-handling.patch assuming it was safe to
treat the return value as an error code, since several uevent functions
returns things like -ENOMEM.

Should I rework the patch as Cornelia suggests and resubmit later, when
things have settled down a little?
