It's correct but not complete. vt6655 impliment their own versions of ethtool_ioctl() when they should be using the standard versions. The vt6655 version of ethtool_ioctl() should be annotated so it's marked that the second parameter is marked as a __user pointer. It doesn't print a Sparse warning because at a certain point Sparse just says: "warning: too many warnings" and gives up. > I haven't signed-off on it yet. > ethtool_ioctl() takes a (void *) as user data, dereferenced and assigend to u32. > applies to next-20140611 It doesn't dereference the pointer. You are getting mixed up with the vt6656 version of ethtool_ioctl() I think? You're not allowed to dereference __user pointers. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
