Kalle Valo says:

====================
wireless-drivers-next patches for v5.5

Second set of patches for v5.5. Nothing special this time, smaller
features to various drivers and of course fixes all over.

Major changes:

iwlwifi

* update scan FW API

* bump the supported FW API version

* add debug dump collection on assert in WoWLAN

* enable adaptive dwell on P2P interfaces

ath10k

* request for PM_QOS_CPU_DMA_LATENCY to improve firmware initialisation time

qtnfmac

* add support for getting/setting transmit power

* handle MIC failure event from firmware

rtl8xxxu

* add support for Edimax EW-7611ULB

wil6210

* add SPDX license identifiers
====================
