From 1795cf48b322b4d19230a40dbe7181acedd34a94 Mon Sep 17 00:00:00 2001 From: Adrian McMenamin Date: Tue, 29 Jul 2008 22:10:56 +0900 Subject: sh/maple: clean maple bus code This patch cleans up the handling of the maple bus queue to remove the risk of races when adding packets. It also removes references to the redundant connect and disconnect functions.
