Merge tag 'iio-for-3.16a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of IIO new driver, functionality and cleanups for the 3.16 cycle.

New device support
* AS3935 Lightning Sensor
* MCP3426/7/8 support added to the existing MCP3422 ADC driver
* AK8963 support in the AK8975 driver
* MPU6500 support in the MPU6050 driver (the functionality that is different
  is mostly not supported yet in either part).

Staging Graduations
* AD799x ADC

New functionality
* ACPI enumeration for the ak8975 driver

Cleanup / tweaks
* Use snprintf as a matter of good practice in a few additional places.
* Document *_mean_raw attributes.  These have been there a while, but were
  undocumented.
* Add an in kernel interface to get the mean values.
* Bug in the length of the event info mask that by coincidence wasn't yet
  actually causing any problems.
* itg3000 drop an unreachable return statement.
* spear_adc cleanups (heading for a staging graduation but a few more
  issues showed up in the review of these patches).
* Exynos ADC dependencies changed so it is only built when Exynos is present
  or COMPILE_TEST and OF are set.
* tsl2583 cleanups.
* Some cut and paste typos in the comments of various drivers still in staging.
* Couple of minor improvements to the ST sensor drivers.

iio: st_sensors: move regulator retrieveal to core

Currently the pressure sensor has code to retrieve and enable two
regulators for Vdd and Vdd IO, but actually these voltage inputs
are found on all of these ST sensors, so move the regulator
handling to the core and make sure all the ST sensors call these
functions on probe() and remove() to enable/disable power.

Here also mover over to obtaining the regulator from the *parent*
device of the IIO device, as the IIO device is created on-the-fly
in this very subsystem it very unlikely evert have any regulators
attached to it whatsoever. It is much more likely that the parent
is a platform device, possibly instantiated from a device tree,
which in turn have Vdd and Vdd IO supplied assigned to it.

The initial state at boot is assumed to be disconnected, and we hope

the _detect() method.

driver, though renamed to that it stays within the namespace associated

This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)

The rcu_assign_pointer() ensures that the initialization of a structure
is carried out before storing a pointer to that structure.
And in the case of the NULL pointer, there is no structure to initialize.
So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL)
