I turned it on, but GCC 4.7.2 doesn't find anything for me. It complains about: if (x != 1 || x != 2) but it doesn't complain about: if (x == 0 || x != 1 || x != 2) Smatch is similar to GCC in this regard... regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
