These three GPIO lines used by the Samsung sensor hub is pretty
straight-forward to convert to use GPIO descriptors.

The charme of devm_* functions is that you don't need to care about them
in the error path. In this case it is valid to just return NULL which makes
the device fail to probe and then the two gpios and the allocated memory
are freed automatically by the driver core.

This driver creates a number of const structures that it stores in the
data field of an of_device_id array.
Add const to the declaration of the location that receives a value
from the data field to ensure that the compiler will continue to check
that the value is not modified and remove the const-dropping cast on
the access to the data field.
Done using Coccinelle.

An spi_driver does not need to set an owner, it will be populated by the

In ancient times it was necessary to manually initialize the bus
field of an spi_driver to spi_bus_type. These days this is done in
spi_register_driver(), so we can drop the manual assignment.

Sensorhub is MCU dedicated to collect data and manage several sensors.
Sensorhub is a spi device which provides a layer for IIO devices. It provides
some data parsing and common mechanism for sensorhub sensors.
Adds common sensorhub library for sensorhub driver and iio drivers
which uses sensorhub MCU to communicate with sensors.
