[ Upstream commit b56511c15713ba6c7572e77a41f7ddba9c1053ec ]
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.
