[alsa-devel] [PATCH v4 2/3] ASoC: wm_adsp: create ALSA controls from wm_adsp driver

[Richard Fitzgerald]

Now that we have a codec_probe stage initialization in the wm_adsp
driver, we can make the wm_adsp driver create its own ALSA controls
instead of having that responsibility pushed to every codec driver.
