Merge tag 'wireless-drivers-next-for-davem-2017-02-16' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
wireless-drivers-next patches for 4.11

Mostly small fixes, not really any new features.

Major changes:

ath10k

* when trying older firmware versions don't confuse user with error messages

ath9k

* fix crash in AP mode (regression)
* fix relayfs crash (regression)
* fix initialisation with AR9340 and AR9550
====================
