dai->probed is used at snd_soc_pcm_dai_probe/remove(),
and used to call real remove() function only when it was probed.
int snd_soc_pcm_dai_probe(...)
{
...
for_each_rtd_dais(rtd, i, dai) {
...
if (dai->driver->probe) {
(A) int ret = dai->driver->probe(dai);
if (ret < 0)
return soc_dai_ret(dai, ret);
}
=> dai->probed = 1;
}
...
}
int snd_soc_pcm_dai_remove(...)
{
...
for_each_rtd_dais(rtd, i, dai) {
...
=> if (dai->probed &&
...) {
...
}
=> dai->probed = 0;
}
...
}
But on probe() case, we need to check dai->probed before calling
real probe() function at (A), otherwise real probe() might be called
multi times (but real remove() will be called only once).
This patch checks it at probe().

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.
