This is not implemented and doesn't really make sense because IIO

Remove IIO_CHAN_INFO_SCALE from info_mask because so that the _scale
sysfs entry won't appear. This fixes userspace tools like generic_buffer
which abort when reads returns an error.

Pull staging and IIO driver updates from Greg KH:
"Here's the big staging and iio driver update for 4.7-rc1.

I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added.

The Lustre developers seem to have woken up from their sleep and have
been doing a great job in cleaning up the code and pruning unused or
old cruft, the filesystem is almost readable :)

Other than that, just a lot of basic coding style cleanups in the
churn. All have been in linux-next for a while with no reported
issues"

Merge tag 'iio-for-4.7b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing

Jonathan writes:

2nd set of new device support, features and cleanup for IIO in the 4.7 cycle.

Bit of a bumper set for new drivers but plenty of other stuff here as well!

New device support
* ad5592R ADC/DAC
- new driver supporting ad5592r and ad5593r combined ADC/DAC and gpio chips.
* Aosong am2315 relative humidity
- new driver with triggered buffer support in follow up patch.
* bmi160 imu
- new driver
* bmp280
- bmp180 support - note there is support in the misc/bmp085 driver. Intent
is to remove that driver long term.
* invensense mpu6050
- cleanup leading to explicit support of mpu9150 with a good few cleanups
along the way.
* Hope RF hp03 pressure and temperature sensor.
- new driver
* maxim DS1803 potentiometer
- new driver
* maxim max44000 light and proximity sensor
- new driver built in a series of steps to support pretty much everything.
* ROHM BH1780 light sensor
- new driver. There is an existing driver in misc that this is pretty much
intended to replace. The discussion on whether to support the non standard
interface of that driver is some way is continuing.
* st-gyro
- lsm9ds0-gyro. The accel/magn side of this will take a while longer as
extensions to the st library are needed for cases where two types of sensor
share a single i2c address.
* ti-adc081c
- support the adc101c and adc121c
* Vishay VEML6070 UV sensor
- new driver.

New features
* core
- devm_ APIs for channel_get and channel_get_all. The first user of these
is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c
- triggered buffer support.

Cleanups
* inkern
- white space fix.
* ad7606
- use the iio_device_claim_direct_mode call rather than open coding equiv.
* ad799x
- white space fix.
* ad9523
- unsigned -> unsigned int
* apds9660
- brace location tidying up.
- silence an uninitialized variable warning.
* ak8975
- else and brace on same line fix.
* at91_adc
- white space fixes.
* bmc150
- use regmap stored copy of the device pointer rather than having an
additional copy.
* bmg160
- use regmap stored copy of the device pointer rather than having an
additional copy.
* hid-sensors
- white space fixes.
* mcp3422
- white space fix.
* mma7455
- use regmap to retrieve the device struct rather than carrying another copy
in the private data.
* ms_sensors
- white space fix.
* mxs-lradc
- move current bindings out of staging - some will be shortly deprecated but
the reality is that we have device trees out there using them so they will
need to be supported for some time. They accidentally got left behind
when the driver graduated from staging.
- white space cleanup.
- set INPUT_PROP_DIRECT.
- move ts config into a better function.
- move the STMP reset out of the ADC init.
* vf610_adc
- case label indenting fix.

max44000: Expose ambient sensor scaling

This patch exposes ALSTIM as illuminance_integration_time and ALSPGA as
illuminance_scale.

Changing ALSTIM also changes the number of bits available in the data
register. This is handled inside raw value reading because:
* It's very easy to shift a few bits
* It allows SCALE and INT_TIME to be completely independent controls
* Buffer support requires constant scan_type.realbits per-channel
