Merge tag 'v5.2-rc6' into rdma.git for-next
For dependencies in next patches. Resolve conflicts: - Use uverbs_get_cleared_udata() with new cq allocation flow - Continue to delete nes despite SPDX conflict - Resolve list appends in mlx5_command_str() - Use u16 for vport_rule stuff - Resolve list appends in struct ib_client Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
