Merge tag 'iwlwifi-next-for-kalle-2017-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next
One more pull-request intended for 4.12. These are the changes:
* The firmware for 7265D and 3168 NICs is frozen at version 29;
* Sari continues working heavily on support for A000 series;
* A bunch of fixes;
* Some cleanups here and there;
