eca7b25bee iio:accel:mma7455_core: Move exports into IIO_MMA7455 namespace
In order to avoid unnecessary pollution of the global symbol namespace
move the core mma7455 functions into an mma7455 specific namespace and
import that into the two bus modules.

For more information see https://lwn.net/Articles/760045/

523742f211 iio: accel: mma7455: Make mma7455_core_remove() return void
Up to now mma7455_core_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.

f414bb19b7 iio: accel: mma7455_i2c: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

a84ef0d181 iio: accel: add Freescale MMA7455L/MMA7456L 3-axis accelerometer driver
Add support for Freescale MMA7455L/MMA7456L 3-axis in 10-bit mode for
I2C and SPI bus. This rather simple driver that currently doesn't
support all the hardware features of MMA7455L/MMA7456L.

Tested on Embedded Artist's LPC4357 Dev Kit with MMA7455L on I2C bus.

Data sheets for the two devices can be found here:
