The binder_deferred_release() function has many levels of indentation
which makes it difficult to read. This patch moves the code which deals
with disposing of a binder node to a separate binder_node_release()
function, thus removing one level of indentation and allowing the code to
fit in 80 columns.

New stuff
1) Add OF support for specifying mappings between iio devices and their
in kernel consumers.
2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and
ad7924 added later in series)
3) Driver for Exynos adc (dt suppor for phy added later in series).
4) Make iio_push_event save IRQ context - necessary if it is to be used
within an interrupt handler. Users of this functionality to follow.
5) For iio use the device tree node name to provide the hwmon name attribute
if available.
Removal and moves out of staging
1) Drop the adt7410 driver from IIO now that there is a hmwon driver with
equivalent support. This device is very much targeted at hardware
monitoring so hwmon is a more appropriate host for the driver.
2) Move iio_hwmon driver to drivers/hwmon.
Cleanups
1) Minor cleanup in ST common library.
2) Large set of patches to break the info_mask element which previously used
odd and even bits to specify if a channel attribute was either shared across
similar channels or specific to only one. Now we have two bitmaps, one for
those parameters that are specific to this channel and one for those shared
by all channels with the same type as this one. This has no effect on the
userspace abi. It simplifies the core code and provides more space for new
channel parameters. It has been on the todo list for a long time!

This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client
for the underlying IIO device channels. Thus a general purpose
IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

The only non move changes here concern the description and changes to the
dependencies to IIO explicit and hwmon implicit.
I'm proposing moving this into hwmon on the basis of placing drivers
based on what they provide rather than what their underlying hardware
is.

So far, all instances of iio_hwmon set their hwmon name attribute
to "iio_hwmon", which is not very descriptive. Set it to the device tree
node name if available, and only revert to iio_hwmon otherwise.
