2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
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.

2010-06-01V4L/DVB: FusionHDTV: Use quick reads for I2C IR device probingJean Delvare
IR support on FusionHDTV cards is broken since kernel 2.6.31. One side effect of the switch to the standard binding model for IR I2C devices was to let i2c-core do the probing instead of the ir-kbd-i2c driver. There is a slight difference between the two probe methods: i2c-core uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As some IR I2C devices only support reads, the new probe method fails to detect them. For now, revert to letting the driver do the probe, using 0-byte reads. In the future, i2c-core will be extended to let callers of i2c_new_probed_device() provide a custom probing function. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: "Timothy D.
