* drm/amd/display: Remove useless comparison of unsigned int vs. 0Alex Hung2024-06-141-7/+4
| | | | | | | | | | | | | | | [WHY & HOW] The comparisons of unsigned int with 0 can have no meanings, i.e. unsigned int >= 0 (always true) or unsigned int < 0 (always false), and therefore they are removed. This fixes 12 NO_EFFECT issues reported by Coverity.
