From 2e3e13f8e9d9b2111404cdccaa4e1b988b70acce Mon Sep 17 00:00:00 2001 From: "Mark M. Hoffman" <mhoffman@lightlink.com> Date: Sun, 6 Nov 2005 23:04:51 +0100 Subject: [PATCH] [PATCH] i2c: i2c-i801 explicitly enables/disables PEC This patch tweaks i2c-i801.c so that the driver always sets the SMBAUXCTL register (which enables/disables PEC) explicitly before each transaction.
