Hi All, I found a small bug in soc-pcm.c. For example, we can see kernel logs as follows:

[ 518.707401] SLIMBUS_0_TX: ASoC: trigger BE MSM8996 Media1 cmd 0 // should be SLIMBUS_0_TX other than MSM8996 Media1 [ 518.707414] MSM8996 Media1: ASoC: post trigger FE MSM8996 Media1 cmd 0

Here is the patch.
