2017-04-02hwmon: (tmp421) Add OF device ID tableJavier Martinez Canillas1-2/+33
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang1-2/+0
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2009-12-14i2c: Drop I2C_CLIENT_INSMOD_2 to 8Jean Delvare1-2/+1

Add support for Texas Instruments TMP421/422/423 temperature sensor IC. TI's TMP421/422/423 are I2C temperature sensor chips. These chips are similar to TI's TMP401/411 chips, but with reduced functionality (only temperature measurement). The chips have one local sensor and up to three (TMP423) remote sensors.
