Subject: ASoC: fsl_audmix: remove "model" attribute
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f2a36a78423ee83b1aac79956891fcad0e833885;p=openwrt%2Fstaging%2Fblogic.git

ASoC: fsl_audmix: remove "model" attribute

Use "of_device_id.data" to specify the machine driver
instead of "model" DTS attribute.
