Subject: [PATCH] data: Clean up expandKeys None value handling
Date: Tue, 26 May 2015 11:41:02 +0100	[thread overview]
Message-ID: <1432636862.404.1.camel@linuxfoundation.org> (raw)

This comparison is interesting even in the case of empty vales. Enabling
this warning actually found a bug in the metadata in avahi. Make the
code handle None specifically and also remove the dead code path in the
second if statement.
