OK, I'll merge with your ack and Cyril's and Richard's suggestion.

I want to fix minimal version as well. Works well on our 3.0 kernel.
Other kernel has a problem 2.6.32-696.el6.x86_64, but IMHO that does not mean
that the test is not valid for this kernel.

./pty04

Can please anybody double check, that with this patch it should be possible to
run this test even on v2.6.25 (which added can module)?

Kind regards,
Petr
