Subject: hwmon: (lm95241) Fix chip detection code
From: Guenter Roeck <guenter.ro...@ericsson.com>
commit 27739e694a3c34b5e371575d74e500d60111c689 upstream.
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.
