[PATCH 01/42] drm/amd/amdgpu/atombios_encoders: Remove set but unused variable 'backlight_level'

From: Lee Jones
Date: Mon Nov 16 2020 - 12:41:37 EST


Also removing the call to amdgpu_atombios_encoder_get_backlight_level_from_reg()
since, according to Alex Deucher, "We call it again below indirectly".

Fixes the following W=1 kernel build warning(s):

drivers/gpu/drm/amd/amdgpu/atombios_encoders.c: In function ‘amdgpu_atombios_encoder_init_backlight’:
drivers/gpu/drm/amd/amdgpu/atombios_encoders.c:174:5: warning: variable ‘backlight_level’ set but not used [-Wunused-but-set-variable]
