From 08c79950a047dbaccf05d70a203db2ee75ac3bd8 Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Wed, 5 Jul 2006 18:14:31 +0200 Subject: hwmon: Add fan speed control features to w83627ehf This patch adds long-awaited support for automatic fan modes. Based on the work of Yuan Mu from Winbond, I finished the support with the great help of David Hubbard.

It is very similar to the IT8712F, so adding support to the it87 driver was pretty straightforward. The most significant change here is that the IT8716F has 16-bit fan speed counters, so the user no more needs to tweak the fan clock dividers to get the best readings. Userspace support is already in lm_sensors SVN (to be soon released as 2.10.1.) Thanks to Stian Oksavik, Olivier Nicolas, Prakash Punnoor and Juergen Kilb for testing the early versions of this patch. Thanks also to ITE for providing datasheets and answering my questions.

Jean Delvare Date: Sun, 24 Sep 2006 21:16:40 +0200 Subject: hwmon: Fix unchecked return status, batch 4 hwmon: Fix unchecked return status, batch 4 Fix up some hwmon drivers so that they no longer ignore return status from device_create_file(). Note: f71805f actually checked the status from device_create_file already. However it did not remove the files on device destruction. It was also an opportunity to use sysfs_create/remove_group instead of hand-made loops. This makes the changes much more important but I think the result is worth it.
