[alsa-devel] [PATCH] ASoC DAPM switching for reentrant codec paths.

[Liam Girdwood]

This patch fixes an issue whereby power was applied to any inactive
analog path that would leave and reenter a codec (e.g. ACOP -> ACIN on
WM8753).  This change now checks for such paths and DAPM will power them
down when not in use.
