The device creator is supposed to use the dev.groups value to add sysfs files before device_add is called, not call sysfs_create_files() after device_add() returns. This creates a race with uevent delivery where the extra attribute will not be visible. This was being done because the groups had been co-opted by the mdev driver, now that prior patches have moved the driver's groups to the struct device_driver the dev.group is properly free for use here.

This is only used by one sample to print a fixed string that is pointless. In general, having a device driver attach sysfs attributes to the parent is horrific. This should never happen, and always leads to some kind of liftime bug as it become very difficult for the sysfs attribute to go back to any data owned by the device driver.
