Subject: linux-next: manual merge of the rdma tree with Linus' tree

Hi Doug,

Today's linux-next merge of the rdma tree got a conflict in:

  drivers/net/ethernet/hisilicon/hns/hns_dsaf_misc.c

between commits:

  a24274aa5c23 ("net: hns: add dsaf misc operation method")
  f00ef863da2b ("net: hns: implement the miscellaneous operation by asl")

from Linus' tree and commit:

  c80815c0b214 ("net: hns: Add reset function support for RoCE driver")

from the rdma tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Stephen Rothwell
