[PATCH 1/2] tools/power/x86/intel-speed-select: Fix display for turbo-freq auto mode

From: Srinivas Pandruvada
Date: Fri Jan 31 2020 - 00:45:35 EST


When mailbox command for the turbo-freq enable fails, then don't display
result for auto-mode. When turbo-freq enable fails, there is no point
to set CPU priorities.
