snd_soc_card_get_codec_dai() can return NULL, but that value is not
checked for, leading to false-positive static analysis warnings
sound/soc/intel/boards/bdw_rt286.c:190:16: error: dereference of NULL
‘codec_dai’ [CWE-476] [-Werror=analyzer-null-dereference]
190 | return snd_soc_component_set_jack(codec_dai->component, NULL, NULL);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
‘card_suspend_pre’: event 1

| | (1) dereference of NULL ‘codec_dai’
This NULL dereference cannot happen, the codec-dai "rt286-aif1" must exists
otherwise the card would not be created. Static analysis cannot know
that however so we might as well squelch this report.

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.
