Subject: [PATCH 4.0 040/148] hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37

4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <linux@...ck-us.net>

commit 9aecac04d8d89e730ae362a748113b19c06a9d39 upstream.

I2C address 0x37 may be used by EEPROMs, which can result in false
positives. Do not attempt to detect a chip at this address.
