Darren Powell ceb180361e amdgpu/pm: Fix possible array out-of-bounds if SCLK levels != 2
[v2]
simplified fix after Lijo's feedback
 removed clocks.num_levels from calculation of loop count
   removed unsafe accesses to shim table freq_values
 retained corner case output only min,now if
   clocks.num_levels == 1 && now > min

 [v1]
added a check to populate and use SCLK shim table freq_values only
   if using dpm_level == AMD_DPM_FORCED_LEVEL_MANUAL or
                         AMD_DPM_FORCED_LEVEL_PERF_DETERMINISM
removed clocks.num_levels from calculation of shim table size
removed unsafe accesses to shim table freq_values
   output gfx_table values if using other dpm levels
added check for freq_match when using freq_values for when now == min_clk

README

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.
