Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull more rdma updates from Jason Gunthorpe: "This is being sent to get a fix for the gcc 9.1 build warnings, and I've also pulled in some bug fix patches that were posted in the last two weeks. - Avoid the gcc 9.1 warning about overflowing a union member - Fix the wrong callback type for a single response netlink to doit - Bug fixes from more usage of the mlx5 devx interface" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: net/mlx5: Set completion EQs as shared resources IB/mlx5: Verify DEVX general object type correctly RDMA/core: Change system parameters callback from dumpit to doit RDMA: Directly cast the sockaddr union to sockaddr
