Almost all default rtd->xxx are setup at soc_new_pcm_runtime()
which is sub-function of snd_soc_add_pcm_runtime() (A).
But "rtd->pmdown_time" is setup at soc_init_pcm_runtime() (B).
It is very random timing setup. This patch setup it at (A),
same as other rtd->xxx.
static int snd_soc_bind_card(...)
{
...
for_each_card_prelinks(...) {
(A) ret = snd_soc_add_pcm_runtime(...);
...
}
...
for_each_card_rtds(...) {
(B) ret = soc_init_pcm_runtime(...);
...
}
...
}
One note is that current topology/intel are directly calling
snd_soc_add_pcm_runtime() (A) without calling soc_init_pcm_runtime() (B).
This means, its "rtd->pmdown_time settings" was 0, but will have default
value by this patch.
"rtd->pmdown_time settings" will be used at
snd_soc_runtime_ignore_pmdown_time(). This patch adds
"ignore_pmdown_time" to these driver to keep compatibility.
bool snd_soc_runtime_ignore_pmdown_time(...)
{
...
=> if (!rtd->pmdown_time || rtd->dai_link->ignore_pmdown_time)
return true;
...
}

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
