From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nathan Chancellor Subject: [PATCH] IB/mlx4: Avoid implicit enumerated type conversion Date: Mon, 24 Sep 2018 12:57:16 -0700 Message-ID: <20180924195716.30848-1-natechancellor@gmail.com> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Doug Ledford , Jason Gunthorpe Cc: linux-rdma@vger.kernel.org, linux-kernel@vger.kernel.org, Nick Desaulniers , Nathan Chancellor List-Id: linux-rdma@vger.kernel.org Clang warns when one enumerated type is implicitly converted to another. drivers/infiniband/hw/mlx4/mad.c:1811:41: warning: implicit conversion from enumeration type 'enum mlx4_ib_qp_flags' to different enumeration type 'enum ib_qp_create_flags' [-Wenum-conversion] qp_init_attr.init_attr.create_flags = MLX4_IB_SRIOV_TUNNEL_QP; ~ ^~~~~~~~~~~~~~~~~~~~~~~ drivers/infiniband/hw/mlx4/mad.c:1819:41: warning: implicit conversion from enumeration type 'enum mlx4_ib_qp_flags' to different enumeration type 'enum ib_qp_create_flags' [-Wenum-conversion] qp_init_attr.init_attr.create_flags = MLX4_IB_SRIOV_SQP; ~ ^~~~~~~~~~~~~~~~~ The type mlx4_ib_qp_flags explicitly provides supplemental values to the type ib_qp_create_flags. Make that clear to Clang by changing the create_flags type to u32.
