From 17acc02c4df45426d62e5e31231a2312c361f107 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 20 Apr 2007 01:43:12 +0200 Subject: [PATCH] hwmon/w83627ehf: Fix the fan5 clock divider write Users have been complaining about the w83627ehf driver flooding their logs with debug messages like: w83627ehf 9191-0a10: Increasing fan 4 clock divider from 64 to 128 or: w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8 The reason is that we failed to actually write the LSB of the encoded clock divider value for that fan, causing the next read to report the same old value again and again. Additionally, the fan number was improperly reported, making the bug harder to find.
