In current ALSA SoC, Codec only has set_bias_level feature. Codec will be merged into Component in next generation ALSA SoC, thus current Codec specific feature need to be merged into it. This is glue patch for it.
Codec side bias related code has .idle_bias_off / .suspend_bias_off too. These are used on dapm_idle_bias_off(), and it will return true if .idle_bias_off was true, then, .suspend_bias_off is not used. Now, Component site is using .idle_bias_off = true now. This patch doesn't convert .idle_bias_off / .suspend_bias_off for Component side, let's use current .idle_bias_off, as-is.
