Subject: [patch (for 2.6.25?) 2/2] RxRPC: fix rxrpc_recvmsg()'s returning of msg_name

From: David Howells <dhowells@...hat.com>

Fix rxrpc_recvmsg() to return msg_name correctly.  We shouldn't overwrite the
*msg struct, but should rather write into msg->msg_name (there's a '&' unary
operator that shouldn't be there).
