Compiling AMD GPU drivers displays two warnings:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_apg.c: In function ‘apg31_se_audio_setup’:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_apg.c:117:18: warning: variable ‘channels’ set but not used [-Wunused-but-set-variable]
and
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_apg.c:116:18: warning: variable ‘speakers’ set but not used [-Wunused-but-set-variable]
Get rid of them by removing the variables and the function
"speakers_to_channels".
