[PATCH net-next 04/14] rxrpc: Replace conn->trans->{local, peer} with conn->params.{local, peer} [ver #2]
From: David Howells
Date: Wed Jun 22 2016 - 12:03:30 EST
Replace accesses of conn->trans->{local,peer} with
conn->params.{local,peer} thus making it easier for a future commit to
remove the rxrpc_transport struct.
This also reduces the number of memory accesses involved.
