Subject: [PATCH BlueZ 10/10] mesh: Clean up Join() method
Date: Thu, 21 May 2020 17:35:01 -0700
Message-ID: <20200522003501.106165-11-inga.stotland@intel.com> (raw)
In-Reply-To: <20200522003501.106165-1-inga.stotland@intel.com>

This consolidates various places where a pending response
to Join() is created and makes sure that l_dus_message_unref()
is called correctly.
