Yeah. If this were a brand new driver then returning -EINVAL would be a good idea. Smatch actually warns about this code as well if you turn on the --spammy option. But there are too many of these kinds of warnings and even I can't check them all so the warning is basically useless. In a few months I will have improved the Smatch code to know that the source string is too large so this bug could have been avoided. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
