From c83c41e4e623aa6504d30c858a05eac771048029 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Thu, 19 Jul 2007 08:00:17 +0200 Subject: hwmon: adm1021 clean ups This patch provides some coding standard cleanups and general code improvements (more debug info, signed values for temperatures, changed names of ADM1023 regs, removed read/write_value functions).

This version has several small fixes for flaws discovered during the review of the first version. This version of the driver does not support the pwm part of these chips (yet). I'll first design a sysfs api for this and post that for discussion, and then implement pwm support as an incremental patch over this one. This driver supports all sensors of this chip, except for the vid inputs. The vid inputs are somewhat documented in the datasheet, but I know nothing about vid/vrm stuff. Help with this would be much appreciated. Signed-off-by: Hans de Goede Acked-by: Darrick J. Wong Signed-off-by: Mark M.

I used a new style suggested by Mark M. Hoffman to retrieve the channel number. Instead of: struct sensor_device_attribute *sda = to_sensor_dev_attr(attr); int nr = sda->index; I do: int nr = to_sensor_dev_attr(attr)->index; This looks better, and even allows the compiler to do some minor optimizations.

(Almost) no functional changes. - Replaced whitespaces with tabs. - Removed empty lines. - Added _i2c_ to names of functions that are strictly I2C related. - Added 4 new functions: dme1737_create_files, dme1737_remove_files, dme1737_sio_enter, and dme1737_sio_exit. - Added error messages in case client attach/detach fails.
