Simple Card Utils has simple_util_dai which is paired to snd_soc_dai,
and assmus that CPU/Codec DAI and its paired simple_util_dai are same
order for CPU/Codec
simple_util_dai[0] <--> snd_soc_dai[0]
simple_util_dai[1] <--> snd_soc_dai[1]
...
So, it is using same index in for_each loop.
(X) gets simple_util_dai
(Y) gets snd_soc_dai
(Y) for_each_rtd_cpu_dais(.., i, ..) {
(X)(A) udai = simple_props_to_dai_cpu(.., i);
}
(X) for_each_prop_dai_cpu(.., i, ...) {
(Y) dai = snd_soc_rtd_to_cpu(.., i);
...
}
But current Simple Card Utils didn't have simple_util_dai for
dummy DAI. So above (A) will get NULL pointer in such case.
This patch cares simple_util_dai for dummy DAI.

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 reStructuredText 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.
