      platform/x86: thinkpad_acpi: Add support for dual fan control · 14232c6e
      Lars Hofhansl authored
      This adds dual fan control for the following models:
      P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.
      
      Both fans are controlled together as if they were a single fan.
      
      Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.
      
      The patch is defensive, it adds only specific supported machines, and falls
      back to the old behavior if both fans cannot be controlled.
      
      Background:
      I tested the BIOS default behavior on my X1E gen2 and both fans are always
      changed together. So rather than adding controls for each fan, this controls
      both fans together as the BIOS would do.
      
      This was inspired by a discussion on dual fan support for the thinkfan tool
      (see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
      verified on my machine.
      
      Thanks to GitHub users voidworker and civic9 for the earlier patches and
      BIOS IDs, and to users peter-stoll and sassman for testing the patch on
      their machines.
