Otherwise, I'll > send you a patch. You should have contacted the lm-sensors mailing-list rather than me directly, so I am replying to this list. I am no more involved in the w83627ehf driver development, but others on the list are. Yuan Mu and Rudolf Marek (in Cc) have been working on extending my preliminary w83627ehf driver, and things are in good shape already, although some more tweaking work seems to be needed. You can certainly help with this, by reviewing and testing Rudolf's version of the patch (he has the latest one and is working on it right now.) Please synchronize with Rudolf (preferably on the list in case others want to participate) so that you don't duplicate the effort. Note that the base for any w83627ehf patch that will be sent to me (as the hwmon subsystem maintainer) now should be based on the w83627ehf driver as found in the latest -mm releases, that is, including this cleanup patch from Yuan Mu: http://khali.linux-fr.org/devel/i2c/linux-2.6/hwmon-w83627ehf-use-attr-arrays.patch Thanks, -- Jean Delvare
