I had a conflict when I applied this to ath-next-test. Please check that
I didn't break anything:

> +	ret = ath10k_wmi_pdev_set_param(ar,

> +	if (ret) {
> +		ath10k_warn("could not init WMI_PDEV_PARAM_ARP_AC_OVERRIDE (%d)\n",
> +			    ret);

I also modified this warning message to follow the style used elsewhere
in the driver.
