Most of the sun8i q8 boards have an SDIO wifi controller, on the variants which use an USB wifi controller, this will result in a couple of error msg-s in dmesg when proving the sdio bus and an used mmc controller. The best way to deal with wifi on this boards really is to simply let the kernel auto-detect usb or sdio wifi controllers, so we will just have to live with the few errors in dmesg. This has been tested on a23 based q8 tablets with ESP8089, RTL8703AS and RTL8189FTV wifi controllers.
