Description OSIDB Bzimport 2024-10-21 19:11:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Initialize denominators' default to 1

[WHAT & HOW]
Variables used as denominators and maybe not assigned to other values,
should not be 0. Change their default to 1 so they are never 0.

This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.
