PM: intel_powerclamp: off by one in start_power_clamp()
This value has already been clamped correctly to 0 through 49 in
powerclamp_set_cur_state() so this patch doesn't actually change
anything. But we should fix it anyway for consistency.
set_target_ratio is used as an offset into an array with
MAX_TARGET_RATIO (50) elements.
