This is a perfect example of what I was talking about in my last email.
The convention here would be to name the main function
__hns_roce_v1_cq_clean and the wrapper hns_roce_v1_cq_clean. Instead,
you have one named cq_clean and one named clean_cq. Keeping straight
which of those locks itself and which needs to be called with the lock
held is nigh impossible.
