0-day rightfully complains about a sometimes uninitialized variable
in pmbus_get_boolean().
drivers/hwmon/pmbus/pmbus_core.c:903:13: warning:
variable 'ret' is used uninitialized whenever 'if' condition is true
} else if (!s1 || !s2) {
While that is technically true, it won't be hit in the field since the
condition indicates a programming error. Move the check of that condition
into the code generating the attribute entry, and refuse generating the
attribute if the condition is true. Swap the condition check in
pmbus_get_boolean() to ensure that static analyzers don't get a hiccup
(because we check if s1 and s2 are NULL, static analyzers may believe
that they can be NULL independently of each other).

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.
