After commite6204f39fe("spi: amd: Drop redundant check"), clang warns (or errors with CONFIG_WERROR=y): drivers/spi/spi-amd.c:695:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] 695 | return ret; | ^~~ drivers/spi/spi-amd.c:673:9: note: initialize the variable 'ret' to silence this warning 673 | int ret; | ^ | = 0 1 error generated. ret is no longer set on anything other than the default switch path. Replace ret with a direct return of 0 at the end of the function and -EOPNOTSUPP in the default case to resolve the warning.

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.
