Problem with the WiFi on IPG-G4-WR-BL module

[bdarek]

I'm having a problem with the WiFi on my IPG-G4-WR-BL module, which is very similar to this one: https://github.com/OpenIPC/wiki/blob/master/en/device-IPC-RM1-BLK7202V3-M43A-WIFI.md. The WiFi chip is an SV6115C. It should work with the ssv6x6x driver, but it doesn't. The dmesg messages are:

ssv6115: loading out-of-tree module taints kernel.
wlan.c ssv_initWlan
ssv_device_init()

*** _ssv_import_default_cfg, (null) ***
