Hi all,

Ahh correct. I will comment it out in example config. Must remained from driver testing.
I will fix it in CVS.

Yes this was already fixed. The driver is now in -mm tree of linux and perhaps will show up in 2.6.14 kernel.
Also the driver now contains latest sysfs subsystem updates and some cleanups. What was paticulary changed
can be seen here: http://assembler.cz/download/w83792d/ (please note that this is not exactly what is in kernel now)

I assume your customer is not running latest kernel so here is the list what you should fix:

0) fix for this update issue (should fix)
1) fix detection probe range (should fix)
2) fix subclient registration (if you want to handle special cases when some of subclients are disabled in HW)
3) fix documentation (should fix)

Fix for 0)
http://lists.lm-sensors.org/pipermail/lm-sensors/attachments/20050706/3a674472/w83792d-driver-QUIET-2.6.x.patch-0001.gz
(in this thread http://lists.lm-sensors.org/pipermail/lm-sensors/2005-July/012919.html)

Fix for 1)

Please add two more addresses so it looks like this:

+/* Addresses to scan */
+static unsigned short normal_i2c[] = { 0x2c, 0x2d, 0x2e, 0x2f, I2C_CLIENT_END };

Fix for 2)

This patch is for modified driver but you should get the idea.

Fix for 3)

Contact at Winbond has been changed. Please ship this version of documenation

>  thank you for your help and your work on lmsensors !

Ahh it always makes me happy :)
