Subject: [PATCH v5 01/16] software node: Allow node creation without properties
Date: Fri, 31 May 2019 17:15:32 +0300
Message-ID: <20190531141547.22728-2-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20190531141547.22728-1-heikki.krogerus@linux.intel.com>

Software nodes are not forced to have device properties.
Adding check to property_entries_dup() to make it possible
to create software nodes that don't have any properties.
