ASoC: soc-pcm: unpack dpcm_set_fe_runtime()
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 dpcm_runtime_setup_fe() (= X),
and setups BE by dpcm_runtime_merge_xxx() (= Y).
(B) static void dpcm_set_fe_runtime(...)
{
...
(X) dpcm_runtime_setup_fe(...);
^ dpcm_runtime_setup_be_format(...);
(Y) dpcm_runtime_setup_be_chan(...);
v dpcm_runtime_setup_be_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.
Now dpcm_set_fe_runtime() (= B) is simple enough and confusable naming,
let's unpack it at dpcm_fe_dai_startup().
