scmi_voltage_descriptors_get() will incorrecly return an error code if the last iteration of the for loop that retrieves the descriptors is skipped due to an error. Skipping an iteration in the loop is not an error, but the `ret` value from the last iteration will be propagated when the function returns. Fix by not saving return values that should not be propagated. This solution also minimizes the risk of future patches accidentally re-introducing this bug.

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.
