c70df20e31 iio: adc: ad7266: claim direct mode during sensor read
Driver was checking for direct mode but not locking it down.
Use iio_device_claim_direct_mode() to guarantee device stays
in direct mode.

06e1b542bb iio:ad7266: Remove redundant call to iio_sw_preenable()
The equivalent of iio_sw_buffer_preenable() is now done in the IIO buffer core,
so there is no need to do this from the driver anymore.

b87fc3e6e2 Staging fixes for 3.8-rc3
Here are a number of small fixes to staging drivers for your 3.8-rc3
 tree.
 
 Well, the omapdrm fixes aren't really "small" but they were waiting on a
 number of other drm patches to go in through the drm tree, and got
 delayed by my vacation over the holidays.  They are totally
 self-contained, everyone involved have acked them, and they fix issues
 that people have been having with the driver.
 
 Other than that one, it's a bunch of tiny bugfixes for a number of
 reported issues.

fc52692c49 Drivers: iio: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

ce56ade6ae iio: Drop timestamp parameter from buffer store_to callback
Drop timestamp parameter from buffer store_to callback and subsequently from
iio_push_to_buffer. The timestamp parameter is unused and it seems likely that
it will stay unused in the future, so it should be safe to remove it.
