From mboxrd@z Thu Jan 1 00:00:00 1970 From: gregkh@suse.de (Greg KH) Date: Fri, 06 Jan 2006 22:07:33 +0000 Subject: [lm-sensors] [PATCH] i2c: i2c-i801 explicitly enables/disables PEC Message-Id: <11365852532723@kroah.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org [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.
