From 27739e694a3c34b5e371575d74e500d60111c689 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 27 Jun 2011 11:22:46 -0700 Subject: [PATCH] hwmon: (lm95241) Fix chip detection code The LM95241 driver accepts every chip ID equal to or larger than 0xA4 as its own, and other chips such as LM95245 use chip IDs in the accepted ID range. This results in false chip detection. Fix problem by accepting only the known LM95241 chip ID.
