commit507397d19bupstream. The regulator_get_voltage() function returns negative error codes. This function saves it to an unsigned int and then does some range checking and, since the error code falls outside the correct range, it returns -EINVAL. Beyond the messiness, this is bad because the regulator_get_voltage() function can return -EPROBE_DEFER and it's important to propagate that back properly so it can be handled.

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.
