* drm/amd/display: Remove useless comparison of unsigned int vs. 0Alex Hung2024-06-143-9/+6
| | | | | | | | | | | | | | | [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.

* drm/amd/display: remove hw access from dc_destroyJun Lei2019-09-132-4/+0
| | | | | | | | | | | | | | | | | | [why] dc_destroy should only clean up SW, this is because GPUs may be removed before driver unload, leading to HW to be unavailable. [how] remove GPIO close as part of GPIO destroy, this is unnecessary because GPIO is not shared, and GPIOs are generally closed after being opened Add tracking to HW access during destructor to make future issues easier to pinpoint, and block access to prevent hangs.
