[PATCH] hwmon: hwmon vs i2c, second round (07/11)
The only part left in i2c-sensor is the VRM/VRD/VID handling code. This is in no way related to i2c, so it doesn't belong there. Move the code to hwmon, where it belongs. Note that not all hardware monitoring drivers do VRM/VRD/VID operations, so less drivers depend on hwmon-vid than there were depending on i2c-sensor.
