Subject: device_register and device_create_file rules

I am aware that it it is always recommended that attributes must be 
associate via attribute groups when calling device_register() .
This way when the device is created, user space can always see 
attributes once they get device create notification via uevent.

I have need to create/delete attributes on fly using 
device_create_file/device_remove_file. In past several drivers did that.

But with the enforcements of device model for new class of drivers, is 
it a big NO? I am not aware of change notification calls other than for 
kobject_uevent.

Thanks,
Srinivas
