Subject: suppress missing attribute warnings
X-Git-Tag: v1.11~17
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6ad43080afda4010f4597f46cd3dd61e49ea11f5;p=users%2Fhch%2Fnvme-cli.git

suppress missing attribute warnings

Attribute existence is dependent on kernel versions. Don't automatically
warn if we fail to find the attribute, let the caller decide how to deal
with it.
