Subject: drm/amdgpu: Drop CONFIG_BACKLIGHT_CLASS_DEVICE ifdefs
Git-commit: 83a3439ddb28e15afa66f52650cf3c1486ae6515
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The DRM_AMDGPU Kconfig code contains:
select BACKLIGHT_CLASS_DEVICE
So the condition these ifdefs test for is always true, drop them.
