Re: [alsa-devel] [PATCH] ASoC: When disabling WM8994 FLL force a source selection

When we disable the WM8994 FLL code path sharing means that we end up writing out a configuration. Currently this is the currently active input and output frequency (which causes snd_soc_update_bits() to suppress actual writes both immediately and in the common case where we reenable the same configuration later) but we allow machine drivers to pass through a source of zero. Since the register values written are one less than the source constants this causes corruption of other bitfields in the register.

Fix this by using the most recently configured FLL source when none is provided.
