Kalle Valo says:

====================
wireless-drivers fixes for 4.12

It has been a slow start of cycle and this the first set of fixes for
4.12. Nothing really major here.

wcn36xx

* fix an issue with module reload

brcmfmac

* fix aligment regression on 64 bit systems

iwlwifi

* fixes for memory leaks, runtime PM, memory initialisation and other
  smaller problems

* fix IBSS on devices using DQA mode (7260 and up)

* fix the minimum firmware API requirement for 7265D, 3168, 8000 and
  8265
====================
