Pull rdma fixes from Jason Gunthorpe: "Not much too exciting here, although two syzkaller bugs that seem to have 9 lives may have finally been squashed. Several core bugs and a batch of driver bug fixes: - Fix compilation problems in qib and hfi1 - Do not corrupt the joined multicast group state when using SEND_ONLY - Several CMA bugs, a reference leak for listening and two syzkaller crashers - Various bug fixes for irdma - Fix a Sleeping while atomic bug in usnic - Properly sanitize kernel pointers in dmesg - Two bugs in the 64b CQE support for hns" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/hns: Add the check of the CQE size of the user space RDMA/hns: Fix the size setting error when copying CQE in clean_cq() RDMA/hfi1: Fix kernel pointer leak RDMA/usnic: Lock VF with mutex instead of spinlock RDMA/hns: Work around broken constant propagation in gcc 8 RDMA/cma: Ensure rdma_addr_cancel() happens before issuing more requests RDMA/cma: Do not change route.addr.src_addr.ss_family RDMA/irdma: Report correct WC error when there are MW bind errors RDMA/irdma: Report correct WC error when transport retry counter is exceeded RDMA/irdma: Validate number of CQ entries on create CQ RDMA/irdma: Skip CQP ring during a reset MAINTAINERS: Update Broadcom RDMA maintainers RDMA/cma: Fix listener leak in rdma_cma_listen_on_all() failure IB/cma: Do not send IGMP leaves for sendonly Multicast groups IB/qib: Fix clang confusion of NULL pointer comparison
