--- Comment #21 from Paulo Nascimento (paulo.ulusu@googlemail.com) ---
I confirm that the bug is not fixed in kenel 5.11-rc3

max brightness:
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/actual_brightness
311
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/brightness
255
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/max_brightness
255

min brightness:
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/actual_brightness
311
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/brightness
0
[pn@pn-legion backlight]$ cat /sys/class/backlight/amdgpu_bl1/max_brightness
255

My laptop has an amd ryzen 5 4600h with renoir igpu and nvidia dgpu. 
Tests are done with renoir igpu:

[pn@pn-legion backlight]$ inxi -G

           Device-2: Advanced Micro Devices [AMD/ATI] Renoir driver: amdgpu v:
