ea9e3f3588 iio:dac: drop assignment of iio_info.driver_module
The equivalent of this is now done via macro magic when
the relevant register call is made.  The actual structure

3704432fb1 iio: refactor info mask and ext_info attribute creation.
Introduce an enum to specify whether the attribute is separate or
shared.

Factor out the bitmap handling for loop into a separate function.

Tidy up error handling and add a NULL assignment to squish a false
positive warning from GCC.

Change ext_info shared type from boolean to enum and update in all
drivers.

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.

dbdc025bb2 staging:iio: Move DAC drivers out of staging
The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.

So lets move the whole folder out of staging.
