From 49ae6cc8005f45edadf237089c31885834f2608e Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Fri, 17 Oct 2008 17:51:11 +0200 Subject: [PATCH] hwmon: (lm87) Fix masking of config register in lm87_init_client() lm87_init_client() conditionally sets the Start bit and clears the INT#_Clear bit in the Config 1 register. The condition should be that either of these bits needs changing, but currently it checks the (self-clearing) Initialization bit instead of INT#_Clear. Fix the condition and also ensure we never set the Initialization bit.
