[WHAT] When compiling Linux kernel with clang, the following warning / error messages pops up: drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml2_0/display_mode_core.c:6853:12: error: stack frame size (2120) exceeds limit (2056) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 6853 | dml_bool_t dml_core_mode_support(struct display_mode_lib_st *mode_lib) [HOW] Refactoring CalculateVMRowAndSwath_params assignments to a new function helps reduce the stack frame size in dml_core_mode_support.

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.
