dpcm_fe_dai_startup() (= A) calls dpcm_set_fe_runtime() (= B) to setup
DPCM runtime. From *naming point of view*, it sounds like setup function
for FE.
(A) static int dpcm_fe_dai_startup(...)
{
...
(B) dpcm_set_fe_runtime(...);
...
}
But in dpcm_set_fe_runtime() (= B),
It setups FE by for_each loop (= X),
and setups BE by dpcm_runtime_merge_xxx() (= Y).
(B) static void dpcm_set_fe_runtime(...)
{
...
^ for_each_rtd_cpu_dais(...) {
| ...
(X) soc_pcm_hw_update_rate(...);
| soc_pcm_hw_update_chan(...);
| soc_pcm_hw_update_format(...);
v }
^ dpcm_runtime_merge_format(...);
(Y) dpcm_runtime_merge_chan(...);
v dpcm_runtime_merge_rate(...);
}
These means that the function which is called as xxx_fe_xxx()
is setups both FE and BE. This is confusable and can be hot bed for bug.
To tidyup it, as 1st step, this patch adds new dpcm_runtime_setup_fe()
for (X).
