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.
