1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.

Maintainer Updates

* Add 3 designated reviewers for IIO.  Lars, Peter and Hartmut have been
  actively reviewing a lot of patches for a while now so this reflects
  the status quo.  These three are probably the only reason I keep
  my head above the water!

New drivers and device support

* max5821 DAC
* Rockchip SARADC
* TI ADC128S052 ADC
* BMC150 Accelerometer
* exynos ADC driver gains support for s3c24xx and s3c64xx parts.
* kxcjk-1013 gainst range control and runtime PM support to drive
  down it's power usage.

Driver removals

* Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple
  basis that they drivers just provided a register write function with
  no compliant user space ABI whatsoever.  Much better to drop them and
  start again for these in the fullness of time.

Core Enhancements

* Join together neighbouring elements in the demux units that feeds
  the binary interfaces.  This cuts down on the number of individual
  copies needed  when splitting out individual channels from the incoming
  channel scans.
* Other demux related cleanups such as using roundup instead of a local
  implementation.

Cleanups

* Drop an unnecessary double setting of the owner field in xilinx adc.
* Some more patches to use managed (devm) interfaces to cut down on
  complexity of removal code.
* adis16060 coding style fixlets.
* Fix some incorrect error returns in the Xilinx ADC driver.
* Coding style fixlets for various accelerometer drivers.
* Some sparse warning fixes to do with endianness and sign of variables.
* Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer
  in hid-sensor-magn-3d by dropping the relevant code.

There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

All what these 'drivers' do is expose a single (non standard ABI) sysfs
attribute that when written to does a direct pass-through to spi_write(). This
is rather ugly and does not justify the existence of a driver as the same can
easily done by using the spidev interface.

The drivers will eventually be rewritten as proper IIO ABI compliant drivers
which do have the proper abstraction layers between userspace and the device.
But in the meantime these driver do not add any extra value and just clutter up
the staging area. So just remove them.

The dgnc_Major_Control_Registered variable purpose was to act as a flag
to indicate if the character device has been successfully registered
into the kernel. This flag was later checked in the module cleanup
function to know if the character device needs to be deregistered.

However the {device,class}_destroy and unregister_chrdev functions may
be called with 'invalid' data perfectly fine. This means that this
variable is not needed and can safely be removed which is what this
commit does.

DBG_PRT uses are unnecessarily complex.

This changes the KERN_<level> type of several uses.
It also enables dynamic_debug for the pr_debug conversions.

This patch can be a prelude to converting these pr_<level>
uses to dev_<level> as appropriate.

Remove now unused static int msglevel declarations.
Remove now unused DBG_PRT #define.

In ll_fault0, the 'fault' struct is mostly cleared before the call to
cl_io_loop, but ft_flags is not reset. It is ordinarily set by
the call to filemap_fault in vvp_io_kernel_fault, but if Lustre
returns before calling filemap_fault, it still has the old value of
ft_flags.

ll_fault0 will then consume the ft_flags field. If it has the
VM_FAULT_RETRY bit set, it will be used as ll_fault0() and
ll_fault()'s return value.

This is a problem when VM_FAULT_RETRY is in ft_flags:
When fault/filemap_fault return with that flag set, they have already
released the mmap semaphore, and do_page_fault does not need to
release it.
Incorrectly returning this flag from ll_fault means mmap_sem
is not upped in the kernel's do_page_fault().

In addition to clearing ft_flags, this patch does not use it unless
it is valid.  It's potentially misleading to return ft_flags in
"fault_ret" if ft_flags has not been set by filemap_fault.

This adds clarity, but does not change the current behavior:
When not valid, ft_flags is replaced by fault_ret, which is zero,
as is ft_flags when not set by filemap_fault.
