Smatch complains that 'str' can be used without being initialized:
drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
error: uninitialized symbol 'str'.
In this loop, we iterate over all the set bits and print the name of the
bit. The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements. If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements. If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".
The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.

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.
