Subject: linux-next: manual merge of the net tree with the net-current tree

Hi all,

Today's linux-next merge of the net tree got a conflict in
net/caif/caif_socket.c between commit
79315068f4560f3f7bd6e9790190dcb43059770c ("caif: fix two caif_connect()
bugs") from the net-current tree and commit
b31fa5bad576cd8180a5ad70c648333b44320d44 ("net/caif: Use pr_fmt") from
the net tree.

I fixed it up (see below) and can carry the fix as necessary.
