The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

There is no need to do the assignment to indio_dev->num_channels in two
lines code.
Put it in one line.

Second set of new driver, functionality and cleanups for IIO in the 4.2 cycle.
Core functionality
* i and q modifiers from quadrature channels.
* IIO_CHAN_INFO_OVERSAMPLING_RATIO added.
* High pass filter attributes added to mirror the existing low pass filter
ones.
Core cleanups
* Make IIO tools building more cross compiler friendly.
* Substantial rework of the function __iio_update_buffers to greatly simplify
a hideously evolved function.
New drivers and support
* ACPI0008 ambient light sensor driver. This one has been around a long time to
will be good to finally get it into mainline.
* Berlin SOC ADC support.
* BMC150 magnetometer. The accelerometer in the same package has been supported
for quite some time, so good to have this half as well.
* m62332 DAC driver
* MEMSIC MMC35420 magnetometer.
* ROHM BH1710 and similar ambient light sensors.
* Sensortek STK3310 light sensor.
* Sensortek STK8312 accelerometer.
* Sensortek STK8BA50 accelerometer.
* ti-adc128s052 gains support form the adc122s021 2 channel ADC.
Driver cleanups and functionality.
* Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled.
* bmc150 - decouple trigger from buffer to allow other triggers to be used.
* bmg160 - decouple trigger from buffer to allow other triggers to be used.
Fix a trivial unused field.
* Constify a load of platform_device_id structures.
* inv_mpu6050 - device tree bindings.
* hid-sensors - fix a memory leak during probe if certain errors occur.
* ltr501 - illuminance channel derived (in an non obvious fashion) from the
intensity channels.
* ltr501 - fix a boundary check on the proximity threshold.
* mlx90614 - drop a pointless return.
* mma8452 - Debugfs register access and fix a bug that had no effect (by
coincidence)
* ti_am335x_adc - add device tree bindings for sample-delay, open-delay and
averaging. The ideal settings for these tend to be board design specific.

The usual mixed bag of fixes for IIO in the 4.1 cycle.
Second version of this pull request as a small fix to a fix turned
up before Greg pulled it for a cc10001 patch near the top of the tree.
One core fix
* Set updated for a iio kfifo was incorrectly set to false during a failed
update, resulting in atttempts to repeat the failed operation appearing
to succeed.
This time I've decided to list the driver fixes in alphabetical order rather
than 'randomly'.
* axp288_adc - a recent change added a check for valid info masks when
reading channels from consumer drivers.
* bmp280 - temperature compensation was failing to read the tfine value, hence
causing a temperature of 0 to always be returned and incorrect presure
measurements.
* cc10001 - Fix channel number mapping when some channels are reserved for
remote CPUs. Fix an issue with the use of the power-up/power-down register
(basically wrong polarity). Fix an issue due to the missinterpretting the
return value from regulator_get_voltage. Add a delay before the start bit
as recommended for the hardware to avoid data corruption.
* hid pressure - fix channel spec of modfiied, but no modifier (which makes no
sense!)
* hid proximity - fix channel spec of modified, but no modifier (which makes
no sense!). Fix a memory leak in the probe function.
* mcp320x - occasional incorrect readings on dma using spi busses due to
cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers.
* mma9551 - buffer overrun fix (miss specified maximum length of buffers)
* mma9553 - endian fix on status message. Add an enable element for activity
channel. Input checking for activity period to avoid rather unpredictable
results.
* spmi-vadc - fix an overflow in the output value normalization seen on some
boards.
* st-snesors - oops due to use of a mutex that is not yet initialized during
probe.
* xilinx adc - Some wrong register addresses, a wrong address for vccaux
channel, incorrect scale on VREFP and incorrect sign on VREFN.

'channels' is allocated via kmemdup and it is never freed.
Use 'indio_dev->channels' directly instead, so that we avoid such
memory leak problem.

Currently in_proximity_(null)_raw is getting presented as raw sysfs
attribute. Same with the scan_elements.
The modifier doesn't apply to this channel.

Add additional flag to read in async mode. In this mode the caller will get
reply via registered callback for capture_sample. Callbacks can be registered
using sensor_hub_register_callback function. The usage id parameter of the
capture_sample can be matched with the usage id of the requested attribute.

IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored
the actual return values (which could be -EINVAL) and instead
returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value
obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO
upon success.

so that sensor is powered off only when last user released it.

Added usage id processing for Proximity (Human Presence).
This uses IIO interfaces for triggered buffer to present data
to user mode. This uses HID sensor framework for registering
