From: zhengbin <zhengbin13@xxxxxxxxxx> [ Upstream commit ac52caecbcf2c30ce95b2536c1caf2643c49b91c ] Fixes gcc '-Wunused-but-set-variable' warning: drivers/gpu/drm/radeon/si_dpm.c: In function si_program_response_times: drivers/gpu/drm/radeon/si_dpm.c:3640:29: warning: variable backbias_response_time set but not used [-Wunused-but-set-variable] It is introduced by commit a9e61410921b ("drm/radeon/kms: add dpm support for SI (v7)"), but never used, so remove it.
