Thanks!
I fixed a few checkpatch warnings and one or two minor matters, the diff is
here. No functional changes. I'm a bit surprised checkpatch.pl suggests to
use numerical values for permissions but I think I agree with that. Reason
is prioritised agains the rules. :-)
Btw. should we update maintainers as well? Would you like to put yourself
there? Feel free to add me, too...
The patches are here. I think they should be good to go to v4.11.
