[alsa-devel] A small bug in soc-pcm.c

[pengdonglin137]

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.
