snd_soc_dai_link_set_capabilities() checks all CPU/Codec DAI (Y)(Z)
for Playback/Capture (X) and checks its validation (A), and setup
dpcm_playback/capture flags (a).
void snd_soc_dai_link_set_capabilities(...)
{
...
(X) for_each_pcm_streams(direction) {
...
(Y) for_each_link_cpus(dai_link, i, cpu) {
...
(A) if (... snd_soc_dai_stream_valid(...)) {
...
}
}
(Z) for_each_link_codecs(dai_link, i, codec) {
...
(A) if (... snd_soc_dai_stream_valid(...)) {
...
}
}
...
}
(a) dai_link->dpcm_playback = supported[...];
(a) dai_link->dpcm_capture = supported[...];
}
This validation check will be automatically done on new
soc_get_playback_capture(). snd_soc_dai_link_set_capabilities() is no
longer needed. Let's remove it.
