Subject: [PATCH] RDMA/hns: Fix build error again
Date: Mon,  7 Oct 2019 23:18:08 +0200	[thread overview]
Message-ID: <> (raw)

This is not the first attempt to fix building random configurations,
unfortunately the attempt in commit a07fc0bb483e ("RDMA/hns: Fix build
error") caused a new problem when CONFIG_INFINIBAND_HNS_HIP06=m

drivers/infiniband/hw/hns/hns_roce_main.o:(.rodata+0xe60): undefined reference to `__this_module'

Revert commits a07fc0bb483e ("RDMA/hns: Fix build error") and
a3e2d4c7e766 ("RDMA/hns: remove obsolete Kconfig comment") to get
back to the previous state, then fix the issues described there
differently, by adding more specific dependencies: INFINIBAND_HNS
can now only be built-in if at least one of HNS or HNS3 are
built-in, and the individual back-ends are only available if
that code is reachable from the main driver.

Fixes: a07fc0bb483e ("RDMA/hns: Fix build error")
Fixes: a3e2d4c7e766 ("RDMA/hns: remove obsolete Kconfig comment")
Fixes: dd74282df573 ("RDMA/hns: Initialize the PCI device for hip08 RoCE")
Fixes: 08805fdbeb2d ("RDMA/hns: Split hw v1 driver from hns roce driver")
