Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma fixes from Jason Gunthorpe:
 "Several regression fixes from work that landed in the merge window,
  particularly in the mlx5 driver:

   - Various static checker and warning fixes

   - General bug fixes in rvt, qedr, hns, mlx5 and hfi1

   - Several regression fixes related to the ECE and QP changes in last
     cycle

   - Fixes for a few long standing crashers in CMA, uverbs ioctl, and
     xrc"
