Hello Bob,

That can't be a problem because:

1. Ouya Inc. doesn't exists anymore.

2. If code was officially published, then this implies that it can be
derived.

3. Ouya's driver uses kernel symbols that are explicitly marked as
GPL-only, see hid_open_report for example. Hence Ouya's driver inherents
the GPL license.

4. Lukas's patch doesn't remind the original code at all.

5. In practice nobody cares about legal much if money aren't involved.
Even if it happened that driver was 100% violating some copyrights, then
it either won't be accepted to upstream or will be removed by request
from the copyrights holder.
