Sorry for that ...

Ok, the driver does not use ioctl only read/write, but the overall
question is, has this driver at all a chance to go into mainline?

I searched for "write a correct" in Documentation but get:

$ grep -lr "write a correct" Documentation/
$

May "Documentation/ioctl/botching-up-ioctls.rst" helps, so I convert
to use the __u* types, thanks!

bye,
Heiko
