Update git submodules

* Update docs/submodules/barometer from branch 'master'
  - Fix test failure condition

    * Because the type of the variable res[3] is bool,
      we should not compare it with a string.
    * The expression "or 'None'" is always the same result,
      because 'None' is a constant value.
      It should be included in the comparison.
