After moving the IO layer inside ASoC to the component level we can now easily move the standard control helpers also to the component level. This allows to reuse the same standard helper control implementations for other components.

I'm running next-20140508 on imx6q-sabresd board and seeing repeated 'amixer: Mixer hw:0 load error: Device or resource busy' message with Debian wheezy rootfs. The git bisect points me to this patch.
== message output before this patch ==
[....] Setting up ALSA...warning: 'alsactl restore' failed with error message 'Found hardware: "wm8962-audio" "" "" "" "" Hardware is initialized using a generic method [ ok tl: set_control:1328: failed to obtain info for control #117 (No such file or directory)'...done.

Why do we start seeing such error message with your patch? Is this a problem of rootfs or kernel?
