Until C++17, a function could not return a tuple using
list-initialization.

g++ (Debian 6.3.0-18) has no problem with -std=c++11.
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.11) failed with:

../src/filesystem/common/CommonDevice.cpp:85:30: error: converting to ‘std::tuple<bool, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >’ from initializer list would use explicit constructor ‘constexpr std::tuple<_T1, _T2>::tuple(_U1&&, _U2&&) [with _U1 = bool; _U2 = const std::__cxx11::basic_string<char>&; <template-parameter-2-3> = void; _T1 = bool; _T2 = std::__cxx11::basic_string<char>]’
             return { true, m };
Fix #54
