From 85f32278bd98fa89dff528b0baea4ae6eea4cc5d Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 4 Apr 2016 14:00:36 +0100 Subject: [PATCH] rxrpc: Replace conn->trans->{local,peer} with conn->params.{local,peer} 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.
