The cur variable indicating the currently selected clock source can be theoretically used as uninitialized after the recent commit481f17c418("ALSA: usb-audio: Handle error for the current selector gracefully"). For addressing it, initialize it before use. Also, one place seems setting 0 to a wrong variable ret, instead of cur; otherwise it makes little sense. Since the initialization is done beforehand, we can get rid of this line, too.

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.
