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

Pull rdma fixes from Jason Gunthorpe:
 "Things have been quite slow, only 6 RC patches have been sent to the
  list. Regression, user visible bugs, and crashing fixes:

   - cxgb4 could wrongly fail MR creation due to a typo

   - various crashes if the wrong QP type is mixed in with APIs that
     expect other types

   - syzkaller oops

   - using ERR_PTR and NULL together cases HFI1 to crash in some cases

   - mlx5 memory leak in error unwind"

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
  RDMA/mlx5: Fix memory leak in mlx5_ib_create_srq() error path

  IB/hfi1: Fix incorrect mixing of ERR_PTR and NULL return values
  RDMA/uverbs: Fix slab-out-of-bounds in ib_uverbs_ex_create_flow
  RDMA/uverbs: Protect from attempts to create flows on unsupported QP
  iw_cxgb4: correctly enforce the max reg_mr depth
