drivers/staging/android: don't use modular references in sync_debug.c

create a 'sync' dir for debugfs information"), modular references were

drivers/staging/android/Makefile:obj-$(CONFIG_SYNC) += sync.o sync_debug.o

drivers/staging/android/Kconfig:        bool "Synchronization framework"

This file isn't currently buildable as a module, and hence the code
for module_exit is just dead code.  Remove it and the module.h include.

Merge tag 'iio-for-4.6b' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

2nd round of new IIO device support, features and cleanups for the 4.6 cycle.

New Device Support
* Apex stx104 DAC
  - new driver for this PC104 board. Right now DAC support only.
* ADI ad5064
  - Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs.
  - Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616,
    ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629.
* ADI ad7192
  - add support for the ad7193
* Invensense mpu6050
  - substantial rework of driver to use regmap allowing SPI support extending
    the now split driver to cover the MPU6000.
* TI adc0832
  - new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs.
* TI ads1015
  - new driver, note that there is an existing hwmon driver. The long term
    intention is to probably remove the hwmon driver but for now we just have
    guards in place to ensure this driver is not built if that one is enabled.
* TI afe4403
  - new driver for this heart rate monitor / pulse oximeter front end chip.
* TI afe4404
  - new driver for this heart rate monitor / pulse oximeter front end chip.

Staging Graduations
* mxs-lradc
  - A combined general purpose and touch screen (input) device driver.
    Originally held in staging to allow reworking into and MFD but as
    that wasn't happening and isn't an absolute requirement we are moving
    it out of staging.

Driver new features
* ms5611
  - triggered buffer support
  - IIO_CHAN_INFO_SCALE to aid the triggered buffer support.

Driver cleanups / reworks / fixes
* ad5064
  - Use an enum for the register map layout to allow support of additional
    chips (precursor to the new support listed above).
  - Structural driver changes to allow support of the slightly different
    handling for the ltc parts above.
* ad5933
  - drop an exceptional & unnecessary for a function pointer.
* ad7606
  - Cleanup the repeated copies of pm ops.
  - consolidate the various channels specs via a sport of rearranging so only
    one version is needed.
* atlas ph sensor
  - add select IRQ_WORK
* hmc8543 (soon to move out of staging)
  - Comment style fixes
  - functionality of suspend and resume was swapped.
* spear-adc
  - use devm_clk_dev instead of managing the clk lifetime by hand.

Core
* Use new dmaengine_terminate_sync call to avoid a theoretical race.
* Fix docs for mlock in struct iio_dev as it is correctly taken in some
  drivers (docs used to say for core only).
* Add a helper function for calculating the scan index storage size within
  the core cutting out some cut and paste versions of the same code.

iio: adc: Add TI ADS1015 ADC driver support

The driver has sysfs readings with runtime PM support for power saving.
It also offers buffer support that can be used together with IIO software
triggers.

Datasheet can be found here:

2-channel 16-bit analog output PC/104 card. The STX104 incorporates a
