Re: [alsa-devel] [PATCH 2/2] ASoC: Disable WM8996 CPVDD supply when not in use

The WM8996 only requires CPVDD when the charge pump is active so control it separately to the other supplies, only enabling it when the charge pump is active. This will result in a small power saving on systems which are able to provide independent software control of the supply.
