Subject: [PATCH rdma-next] RDMA/cxgb4: Remove unnecessary conversion from __be32 to cpu format
Date: Tue, 24 Oct 2017 21:28:48 +0300	[thread overview]
Message-ID: <20171024182848.7945-1-leon@kernel.org> (raw)

The scqe.stag is actually declared in u32 format and don't need
conversion from __be32 to cpu format.

Remove the be32_to_cpu() and avoid the following sparse error.
  drivers/infiniband/hw/cxgb4/cq.c:754:52: warning: cast to restricted __be32
