Michal Suchanek 2fee899c06 perf hwmon_pmu: Fix uninitialized variable warning
The line_len is only set on success. Check the return value instead.

 util/hwmon_pmu.c: In function ‘perf_pmus__read_hwmon_pmus’:
 util/hwmon_pmu.c:742:20: warning: ‘line_len’ may be used uninitialized [-Wmaybe-uninitialized]
   742 |                 if (line_len > 0 && line[line_len - 1] == '\n')
       |                    ^
 util/hwmon_pmu.c:719:24: note: ‘line_len’ was declared here
   719 |                 size_t line_len;

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 reStructuredText 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.
