Kalle Valo says:

====================
wireless-drivers-next patches for 4.15

The first pull request for 4.15, unusually late this time but still
relatively small. Also includes merge from wireless-drivers to fix
conflicts in iwlwifi.

Major changes:

rsi

* add P2P mode support

* sdio suspend and resume support

iwlwifi

* A fix and an addition for PCI devices for the A000 family

* Dump PCI registers when an error occurs, to make it easier to debug

rtlwifi

* add support for 64 bit DMA, enabled with a module parameter

* add module parameter to enable ASPM
