From a8299ec1b243ea56c41648ca63b96930f2db118b Mon Sep 17 00:00:00 2001 From: Mao Zhongyi Date: Mon, 22 Oct 2018 15:40:49 +0800 Subject: [PATCH] audio: use object link instead of qdev property to pass wm8750 reference MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to qdev-properties.h, properties of pointer type should be avoided, it seems a link type property is a good substitution.
