====================
wireless-drivers fixes for 5.0

First set of small, but importnat, fixes for 5.0.

iwlwifi

* fix a build regression introduced in 5.0-rc1

wlcore

* fix a firmware regression from v4.18-rc1

mt76x0

* fix for configuring tx power from user space

ath10k

* fix wcn3990 regression from v4.20-rc1
