target/mips/op_helper.c:971:duplicated branches ?

qemu-4.2.0/target/mips/op_helper.c:971:8: warning: this condition has identical branches [-Wduplicated-branches]

Source code is

   if (other_tc == other->current_tc) {
        tccause = other->CP0_Cause;
    } else {
        tccause = other->CP0_Cause;
    }

Possible cut'n'paste error ?
