Subject: [PATCH AUTOSEL 4.14 233/371] ASoC: ti: davinci-mcasp: Fix slot mask settings when using multiple AXRs
From: Peter Ujfalusi <peter.ujfalusi@...com>
[ Upstream commit fd14f4436fd47d5418023c90e933e66d3645552e ]
If multiple serializers are connected in the system and the number of
channels will need to use more than one serializer the mask to enable the
serializers were left to 0 if tdm_mask is provided
