Subject: drm/radeon: remove set but not used variable 'backbias_response_time'
Git-commit: ac52caecbcf2c30ce95b2536c1caf2643c49b91c
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
