[alsa-devel] [PATCH] ASoC: da7210: Minor bugfix for non pll slave mode

[Ashish Chavan]

This patch fixes a bug discovered during testing of non pll slave mode.
Due to the bug chip was not getting correctly configured and as a result
there was no sound output while playback. After applying this patch,
both pll and non pll modes work fine.
