This patch (and the other) have been in Mark's tree for a month or so. (linux-next <- useful!) Mark has been pretty, umm, low-key lately. I've attached the full git-hwmon changelog below and the authors of all those changes are cc'ed. Could people please confirm that what is in linux-next is still the latest and greatest version of their changes? If so, I shall plan on fishing those changes out of there and getting them into -rc2. Thanks. commit 530598a47e8562f680d155eb280dddd6af1b3d9e Author: Jean Delvare Date: Wed Jun 25 09:10:30 2008 -0400 hwmon: (lm85) Simplify device initialization function Clean up and simplify the device initialization function: * Degrade error messages to warnings - what they really are. * Stop warning about VxI mode, we don't really care. * Drop comment about lack of limit initialization - that's the standard way, all hardware monitoring drivers do that. * Only read the configuration register once. * Only write back to the configuration register if needed. * Don't attempt to clear the lock bit, it locks itself to 1. * Move the function to before it's called, so that we no longer need to forware declare it.

This is a bad idea as we have no guarantee that the cache is up-to-date. Better read a fresh register value from the chip, it's safer and in fact it is also more simple.

Chips are put into 9-bit mode so the current interconversion routines will never fail. - Save the original chip configuration, and restore it on exit. (Among other things, this normally turns off the mode where the chip is constantly sampling ... and thus saves power.) So the new-style code should catch all chips that boards declare, while the legacy code catches others. This particular coexistence strategy may need some work yet ... legacy modes might best be set up explicitly by some tool not unlike "sensors-detect". (Or else completely eradicated...)

One driver binding function moved out of the attribute section, as did the driver struct itself. - Minor tweaks to legacy probe logic: correct a comment, and remove a pointless variable. - Whitespace, linelength, and comment fixes. This patch should include no functional changes. It's preparation for adding new-style (driver model) I2C driver binding.
