Description

This is an issue on amd-staging-drm-next but not on 4.19.7. I have not tested other kernels. The issue is that if you put the system in suspend and wake it up again, the backlight is off. On 4.19 when you resume from suspend the backlight resumes the same level it was when you put it into suspend.
