If the system -is currently in runtime suspend, it is necessary to wake up the device, -and then make it ready. Currently, the wake does not correctly resync -the device, which may mean it cannot suspend correctly. Fix this by -performaing a resync. - -Signed-off-by: Stefan Binding <sbinding@opensource.cirrus.com> ---- - sound/pci/hda/cs35l41_hda.c | 32 +++++++++++++++++++++++++++----- - 1 file changed, 27 insertions(+), 5 deletions(-) - -diff --git a/sound/pci/hda/cs35l41_hda.c b/sound/pci/hda/cs35l41_hda.c -index 29f1dce45f1d..f42457147ce4 100644 ---- a/sound/pci/hda/cs35l41_hda.c -+++ b/sound/pci/hda/cs35l41_hda.c -@@ -574,21 +574,43 @@ static int cs35l41_hda_channel_map(struct device *dev, unsigned int tx_num, unsi - rx_slot);
