[PATCH 2/2] ASoC: trace: add event to snd_soc_dapm trace events

[Luca Ceresoli]

Add the event value to the snd_soc_dapm_start and snd_soc_dapm_done trace
events to make them more informative.

Trace before:

           aplay-229   [000]   250.140309: snd_soc_dapm_start:   card=vscn-2046
           aplay-229   [000]   250.167531: snd_soc_dapm_done:    card=vscn-2046
           aplay-229   [000]   251.169588: snd_soc_dapm_start:   card=vscn-2046
           aplay-229   [000]   251.195245: snd_soc_dapm_done:    card=vscn-2046

Trace after:

           aplay-214   [000]   693.290612: snd_soc_dapm_start:   card=vscn-2046 
event=1
           aplay-214   [000]   693.315508: snd_soc_dapm_done:    card=vscn-2046 
event=1
           aplay-214   [000]   694.537349: snd_soc_dapm_start:   card=vscn-2046 
event=2
           aplay-214   [000]   694.563241: snd_soc_dapm_done:    card=vscn-2046 
event=2
