So a colleague of mine tested this and came up with a conclusion that expressions in Kconfig can only deal with boolean or tristate operands and no casting is made with strings. Using any string operand as part of a boolean expression is simply a type error and Kconfig probably marks such operand as 'n', regardless of its value.
