Re: [PATCH] I2C update for 2.6.8-rc1

[Greg KH <greg@kroah.com>]

ChangeSet 1.1784.13.13, 2004/07/14 11:50:09-07:00, mhoffman@lightlink.com

[PATCH] I2C: Remove extra inits from lm78 driver

This patch is from the lm_sensors project CVS, from this revision:

	1.63 (mds) remove initialization of limits by driver

It is better to set these limits by a combination of /etc/sensors.conf
and 'sensors -s'; "mechanism not policy."  Please apply.
