Since commit13f58267cd("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()") dummy snd_soc_dai_link.codecs entries no longer have a name set. This means that when looking for the codec dai_link the machine driver can no longer unconditionally run strcmp() on snd_soc_dai_link.codecs[0].name since this may now be NULL. Add a check for snd_soc_dai_link.codecs[0].name being NULL to all BYT/CHT machine drivers to avoid NULL pointer dereferences in their probe() methods.

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.
