I have only sent what I thought is appropriate for 4.18 (cleanup/features 
will be sent separately):

* 5 bug fixes (1-5/7)
* 1 update the maintainer list (7/7)
* 1 update to the comment to prevent checkpatch from complaining (6/7)

If you think any patch is unsuitable to 4.18 - please say which.

Thanks,
Nadav
