* staging: Use GFP_ATOMIC when a lock is heldJulia Lawall2010-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In each case, the containing function is only called from one place, where a spin lock is held.

* i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang2010-06-032-4/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version has the right part number in the commit message. Whilst technically the part I listed last time is also supported by the driver, the commit message might have caused confusion. Another driver from Barry at Analog. Again, I've lifted if from the blackfin tree and done the usual sparse and checkpatch fixes + the abi changes. I actually have one of these, so am particularly pleased to see it supported!

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains fixes for the two bugs Michael pointed out last week. As the other suggestion Michael made is not a bug fix (just a much more sensible way of handling things), I'll do that as a separate patch soon. The bugs were introduced with the abi changes.
