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

Pull rdma fixes from Doug Ledford:
 "I'm back from PTO.  These issues cropped up while I was gone and are
  simple fixes.  I'll have more after I've caught up, but I wanted to
  get these in quick.

  Two minor fixes for 4.6-rc2:

   - Fix mlx5 build error when on demand paging is not enabled

   - Fix possible uninit variable in new i40iw driver"

* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma:
  i40iw: avoid potential uninitialized variable use
  IB/mlx5: fix VFs callback function prototypes
