If the line is set to be open drain, also tag on IRQF_SHARED

iio: st_sensors: read each channel individually
The current buffer read code tries to optimize reads from the
sensor data registers by issuing a single read operation across
all the indata registers.
This doesn't work: when the LIS331DL accelerometer sensor is
configured to open drain, active low interrupt mode, this will
just clear the XDA (X-axis data available) bit in the STATUS_REG
register (0x27), while YDA, ZDA and even ZYXDA remain set to 1,
and the internal logic of the sensor holds the DRDY (INT1) line
asserted (the value of the status register is 0xee).
If we instead issue one read operation per enabled channel
(X, Y, Z) things start working and we can use open drain and
active low interrupts.
Note that a backported patch fixing this issue will be heading
via the fixes branch but changes in this file already in staging-next
will make that patch 'look' rather different. The code in here
is the correct one when that clash hits.

iio: imu: Add initial support for Bosch BMI160
BMI160 is an Inertial Measurement Unit (IMU) which provides acceleration
and angular rate measurement. It also offers a secondary I2C interface
for connecting a magnetometer sensor (usually BMM160).
Current driver offers support for accelerometer and gyroscope readings
via sysfs or via buffer interface using an external trigger (e.g.
hrtimer). Data is retrieved from IMU via I2C or SPI interface.
Datasheet is at:

iio: dht11: Improve logging
* Unify log messages
* Add more DEBUG messages
Apparently this driver is working unreliably on some platforms that I can't
test. Therefore I want an easy way for bug reporters to provide useful
information without making the driver too chatty by default.
