0aa3f139cd staging: Use GFP_ATOMIC when a lock is held
In each case, the containing function is only called from one place, where
a spin lock is held.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@gfp exists@
identifier fn;
position p;
@@

fn(...) {
... when != spin_unlock
    when any
  GFP_KERNEL@p
 ... when any
}

@locked@
identifier gfp.fn;
@@

spin_lock(...)
... when != spin_unlock
fn(...)

@depends on locked@
position gfp.p;
@@

- GFP_KERNEL@p
+ GFP_ATOMIC
// </smpl>

fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
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
e4a7b9b04d 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 required a bit of hand merging due to the conflicts
that happened in the later .34-rc releases, as well as
some staging driver changing coming in through other trees
(v4l and pcmcia).

5763dcab5c staging: iio: adis16350 and similar IMU driver
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!

81b77f94a1 Staging: iio: max1363 Fix two bugs in single_channel_from_ring
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.
