Subject: [PATCH 5.3 031/140] ASoC: msm8916-wcd-digital: add missing MIX2 path for RX1/2

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

[ Upstream commit bcab05880f9306e94531b0009c627421db110a74 ]

This patch adds missing MIX2 path on RX1/2 which take IIR1 and
IIR2 as inputs.

Without this patch sound card fails to intialize with below warning:

 ASoC: no sink widget found for RX1 MIX2 INP1
 ASoC: Failed to add route IIR1 -> IIR1 -> RX1 MIX2 INP1
 ASoC: no sink widget found for RX2 MIX2 INP1
 ASoC: Failed to add route IIR1 -> IIR1 -> RX2 MIX2 INP1
 ASoC: no sink widget found for RX1 MIX2 INP1
 ASoC: Failed to add route IIR2 -> IIR2 -> RX1 MIX2 INP1
 ASoC: no sink widget found for RX2 MIX2 INP1
 ASoC: Failed to add route IIR2 -> IIR2 -> RX2 MIX2 INP1
