Merge tag 'wireless-drivers-2019-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers

Kalle Valo says:

====================
wireless-drivers fixes for 5.4

Third set of fixes for 5.4. Most of them are for iwlwifi but important
fixes also for rtlwifi and mt76, the overflow fix for rtlwifi being
most important.

iwlwifi

* fix merge damage on earlier patch

* various fixes to device id handling

* fix scan config command handling which caused firmware asserts

rtlwifi

* fix overflow on P2P IE handling

* don't deliver too small frames to mac80211

mt76

* disable PCIE_ASPM

* fix buffer DMA unmap on certain cases
====================
