The Linux ThinkPad community is not positive that all ThinkPads that do HFSP EC fan control do implement full-speed and auto modes, some of the earlier ones supporting HFSP might not. If the EC ignores the AUTO or FULL-SPEED bits, it will pay attention to the lower three bits that set the fan level. And as thinkpad-acpi was leaving these set to zero, it would stop(!) the fan, which is Not A Good Thing. So, as a safety net, we now make sure to also set the fan level part of the HFSP register to speed 7 for full-speed, and a minimum of speed 4 for auto mode.
