Subject: Re: [PATCH 1/1] Add mkopci driver

But the driver is really very insignificant.
I was wondering about sysfs before, but consumers will not be very happy to get another revision of userspace tools/library.
So this is their own problems :)

Thanks again and sorry for this uselessness dialogue :)
