If you say yes here you get support for ITE IT8705F, IT8712F,
IT8716F, IT8718F, IT8720F, IT8721F, IT8726F, IT8728F, IT8758E,
IT8782F, and IT8783E/F sensor chips, and the SiS950 clone.
IT8771E, IT8772E, IT8782F, and IT8783E/F sensor chips, and the
SiS950 clone.
This driver can also be built as a module. If so, the module
will be called it87.
