commit: 41002f8dd5938d5ad1d008ce5bfdbfe47fa7b4e8 From: Jean Delvare <[email protected]> Date: Thu, 12 Jul 2012 22:47:37 +0200 Subject: hwmon: (it87) Preserve configuration register bits on init
We were accidentally losing one bit in the configuration register on device initialization. It was reported to freeze one specific system right away. Properly preserve all bits we don't explicitly want to change in order to prevent that.
