linux-next: manual merge of the block tree with the net-next tree

[Mark Brown]

Hi all,

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

  io_uring/zcrx.c

between commit:

  222b5566a02dbf ("net: Proxy netdev_queue_get_dma_dev for leased queues")

from the net-next tree and commit:

  06fc3b6d388dfa ("io_uring/zcrx: extract netdev+area init into a helper")

from the block 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.
