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

Hi Nicholas,

Today's linux-next merge of the target-updates tree got a conflict in
drivers/target/target_core_user.c between commit 9c1cd1b68cd1
("target/user: Only support full command pass-through") from Linus'
tree and commit 1f44c7e00856 ("target: simplify backend driver
registration") and 1854440347ec ("target: consolidate backend attribute
implementations") from the target-updates tree.

I fixed it up (just this file - see below - I hope that the rest was
taken care of) and can carry the fix as necessary (no action is
required).

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
