commit 0145b50566e7de5637e80ecba96c7f0e6fff1aad upstream.
Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.
This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.
While at it, this commit also fixes up some neighboring lines where
statements were needlessly split over 2 lines to improve readability.

The equivalent of this is now done via macro magic when
the relevant register call is made. The actual structure
elements will shortly go away.

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

The platform_device_id is not modified by the driver and core uses it as
const.

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.

Use common hid sensor iio pm functions. Also the poll time read and
wait is part of power up function of hid sensor iio pm function, so
remove from the client drivers.

This patch removes the .owner field for drivers which use the
platform_driver_register api because this is overriden in
_platform_driver_register.

Added support for raw reading of channel. If the sensor is powered
off, it will turn on for reading value.

Added an API to allow client drivers to turn ON and OFF sensors for
quick read. Added data_read as counting varaible instead of boolean,
so that sensor is powered off only when last user released it.

Added usage id processing for Inclinometer 3D. This uses IIO
interfaces for triggered buffer to present data to user
mode.This uses HID sensor framework for registering callback
events from the sensor hub.
