[PATCH AUTOSEL 6.1 6/9] ASoC: fsl_audmix: register card device depends on 'dais' property

[Pavel Machek]

Hi!

> 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.

This is part of series, AFAICT; should we have it in -stable?

Best regards,
