My bad it seems my tree is bit older, sorry for the confusion.
Also I noticed, .wmi_init_config of ipq8074_ops is registered with " 
ath11k_init_wmi_config_qca6390()" Is that correct?
If that is correct,  then I don't see ath11k_init_wmi_config_ipq8074() 
is called from any other place.
I will send one patch to fix this issue. Please correct me if I am 
wrong.
