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. Signed-off-by: Seth Forshee <seth.forshee@xxxxxxxxx> Signed-off-by: Liam Girdwood <lg@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
