I'm not sure how this code has been designed, though uuid_le followed by guid_t are kernel internal types mistakenly put to UAPI in the first place.

It will work still the same after this change. -- With Best Regards, Andy Shevchenko _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
