According to the current code, you will print this error together with
error line in hns_roce_register_device for the same failure.
"ib_register_device failed!"
"register_device failed!"
Hi, leon
In this patch [PATCH v9 11/22], there is only one error branch in
funtion named hns_roce_register_device.
In the following patch [PATCH v9 13/22], we add more operation,
there are more
than two error branch in this function as below.
