ASoC: soc-pcm.c: remove indirect runtime copy
substream->runtime will be attached when substream was opened
at snd_pcm_attach_substream(). When it uses DPCM,
FE substream->runtime is attached, but BE substream->runtime is not.
Thus, we are copying FE substream->runtime to BE.
But, we are copyig FE substream->runtime to FE dpcm->runtime first (A),
and copy it to BE dpcm->runtime (B), and copy it to
BE substream->runtime (C).
static int dpcm_fe_dai_open(...) {
...
(A) fe->dpcm[stream].runtime = fe_substream->runtime;
...
}
static int dpcm_be_connect(...) {
...
(B) be->dpcm[stream].runtime = fe->dpcm[stream].runtime;
...
}
int dpcm_be_dai_startup(...) {
...
(C) be_substream->runtime = be->dpcm[stream].runtime;
...
}
It is too roundabout and troublesome.
OTOH, it is directly copying fe_substream->runtime at dpcm_be_reparent()
without using be->dpcm[stream].runtime.
static void dpcm_be_reparent(...)
{
...
for_each_dpcm_fe(be, stream, dpcm) {
...
=> be_substream->runtime = fe_substream->runtime;
break;
}
}
This patch removes indirect copying.
