Clang warns: sound/soc/amd/ps/pci-ps.c:218:2: error: variable 'ret' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized] default: ^~~~~~~ sound/soc/amd/ps/pci-ps.c:239:9: note: uninitialized use occurs here return ret; ^~~ sound/soc/amd/ps/pci-ps.c:190:9: note: initialize the variable 'ret' to silence this warning int ret; ^ = 0 1 error generated. ret is used uninitialized if 'goto de_init' is taken. As this is not an error nor should the ACP be deinitialized, just directly return 0 in this case statement, which resolves 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 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.
