Uwe Kleine-König f23215c1e5 iio: magnetometer: bmc150_magn_i2c: Convert to i2c's .probe_new()
.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

Uwe Kleine-König ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Uwe Kleine-König d04d46dd82 iio:magnetometer:mbc150: Make bmc150_magn_remove() return void
bmc150_magn_remove() always returns zero. Make it return no value which
makes it easier to see in the callers that there is no error to handle.

Also the return value of i2c driver remove callbacks is ignored anyway.
This prepares making i2c remove callbacks return void, too.

Jonathan Cameron 47d6cae0d0 iio:magnetometer:bmc150: Move exports to IIO_BMC150_MAGN namespace
In order to avoid unnecessary pollution of the global symbol namespace
move the common/library functions into a specific namespace and import
that into the bus specific device drivers that use them.

Note the MAGN postfix here is reflecting that this driver is only
responsible for part of the BMC150 device.

Javier Martinez Canillas 49926b1216 iio: magnetometer: bmc150_magn_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.

Daniel Baluta 761b7910d4 iio: magn: Split bmc150 driver in common/i2c parts
This is useful for easily adding SPI support in later patches.

Now bmc150_magn exports core functions to be used by I2C/SPI drivers
instances. For the moment only I2C driver is supported.
