From: Shengjiu Wang <redacted> [ Upstream commit 294a60e5e9830045c161181286d44ce669f88833 ] In order to make the audmix device linked by audio graph card, make 'dais' property to be optional. If 'dais' property exists, then register the imx-audmix card driver. otherwise, it should be linked by audio graph card.
