[WHY] Coverity analysis of the Upstream display driver code (amd-staging-drm-next) flagged these three functions as containing 'CONSTANT_EXPRESSION_RESULT' errors, i. e. the conditionals are reduntant since their result is predetermined. fixpt31_32.c: The two flagged 'ASSERT' lines redundant since they are always true: - LONG_MAX equals to the largest 'signed long long' number - res.value is type 'signed long long', So, the condition inside the 'ASSERTS's is always link_dp_training.c: The flagged conditional statement is always false: - 'max_requested.FFE_PRESET.settings.level' is 4 bits, so its max possible value is 15 - 'DP_FFE_PRESET_MAX_LEVEL' equals to 15. So, the conditional statement is always false and the wrapped code never executes. [HOW] Removed lines flagged by Coverity analysis.

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.
