From 49bb0943329929e73c9a22c97d53c6c8967eb243 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 3 Feb 2011 08:23:10 +0000 Subject: [PATCH] radeonfb: Let hwmon driver probe the "monid" I2C bus Some Radeon cards have an I2C-based thermal sensor chip connected to the "monid" I2C bus. Set the I2C probing class of this bus properly so that hwmon drivers can detect devices on it and bind to them. This closes kernel.org bug #26172. We exclude PPC for the time being, as Benjamin doesn't want us to mess up with them without explicit testing, and there is no evidence that this change is needed for them either.
