    Thsrs is no way to tell gcc that an inline asm doesn't return. The only
    way to do it would be to add something like a "for (;;);" (that gcc will
    actually generate real code for) inside the BUG() macro, but I'd hate to
    do that.

    Better to just initialize the variable to a default value and avoid the
    warning for now.
