clang warns (or errors with CONFIG_WERROR=y):
sound/soc/codecs/cs42l43.c:1371:2: error: variable 'ret' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
1371 | default:
| ^~~~~~~
sound/soc/codecs/cs42l43.c:1377:9: note: uninitialized use occurs here
1377 | return ret;
| ^~~
sound/soc/codecs/cs42l43.c:1349:9: note: initialize the variable 'ret' to silence this warning
1349 | int ret;
| ^
| = 0
1 error generated.
Initialize ret to 0 in the default case, as there was nothing to do for
other event types.

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.
