No rush with testing, this is just a status update.

I've reverted the previous patch "fix WCN6750 firmware crash" in my branch and applied this one and everything still looks fine. Thanks! Tested-by: Luca Weiss <luca.weiss@fairphone.com> Regards Luca

WCN6750 firmware crashes because of num_vdevs changed from 4 to 17 in ath11k_init_wmi_config_qca6390() as the ab->hw_params.num_vdevs is 17. This is caused by commit f019f4dff2e4("wifi: ath11k: support 2 station interfaces") which assigns ab->hw_params.num_vdevs directly to config->num_vdevs in ath11k_init_wmi_config_qca6390(), therefore WCN6750 firmware crashes as it can't support such a big num_vdevs. Fix it by assign 3 to num_vdevs in hw_params for WCN6750 as 3 is sufficient too.
