Kalle Valo says:

====================
wireless-drivers fixes for 4.9

iwlwifi

* some fixes for suspend/resume with unified FW images
* a fix for a false-positive lockdep report
* a fix for multi-queue that caused an unnecessary 1 second latency
* a fix for an ACPI parsing bug that caused a misleading error message

brcmfmac

* fix a variable uninitialised warning in brcmf_cfg80211_start_ap()
====================
