13 ASoC: trace: add component to set_bias_level trace events
14
15 The snd_soc_bias_level_start and snd_soc_bias_level_done trace events
16 currently look like:
17
18 aplay-229 [000] 1250.140778: snd_soc_bias_level_start: card=vscn-2046 val=1
19 aplay-229 [000] 1250.140784: snd_soc_bias_level_done: card=vscn-2046 val=1

21 aplay-229 [000] 1250.140788: snd_soc_bias_level_done: card=vscn-2046 val=2
22 kworker/u8:1-21 [000] 1250.140871: snd_soc_bias_level_start: card=vscn-2046 val=1
23 kworker/u8:0-11 [000] 1250.140951: snd_soc_bias_level_start: card=vscn-2046 val=1
24 kworker/u8:0-11 [000] 1250.140956: snd_soc_bias_level_done: card=vscn-2046 val=1
25 kworker/u8:0-11 [000] 1250.140959: snd_soc_bias_level_start: card=vscn-2046 val=2
26 kworker/u8:0-11 [000] 1250.140961: snd_soc_bias_level_done: card=vscn-2046 val=2

28 kworker/u8:1-21 [000] 1250.167222: snd_soc_bias_level_start: card=vscn-2046 val=2
29 kworker/u8:1-21 [000] 1250.167232: snd_soc_bias_level_done: card=vscn-2046 val=2
30 kworker/u8:0-11 [000] 1250.167440: snd_soc_bias_level_start: card=vscn-2046 val=3
31 kworker/u8:0-11 [000] 1250.167444: snd_soc_bias_level_done: card=vscn-2046 val=3
32 kworker/u8:1-21 [000] 1250.167497: snd_soc_bias_level_start: card=vscn-2046 val=3
33 kworker/u8:1-21 [000] 1250.167506: snd_soc_bias_level_done: card=vscn-2046 val=3
34
35 There are clearly multiple calls, one per component, but they cannot be
36 discriminated from each other.
37
38 Change the ftrace events to also print the component name, to make it clear
39 which part of the code is involved. This requires changing the passed value
40 from a struct snd_soc_card, where the DAPM context is not kwown, to a
41 struct snd_soc_dapm_context where it is obviously known but the a card
42 pointer is also available.
43
44 With this change, the resulting trace becomes:
45
46 aplay-247 [000] 1436.357332: snd_soc_bias_level_start: card=vscn-2046 component=(none) val=1
