[PATCH 0/2 V2] iio: magnetometer: ak8975: Add support for DT and interrupt handling

[Jacek Anaszewski <j.anaszewski-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>]

These patches add 'data ready' interrupt handling for AK8975
magnetometer, so as to provide more efficient alternative of
waiting for the end of conversion. This short series adds also
support for parsing 'gpios' property when initializing from oftree.

This is a follow-up of the previous patchset and it includes
following improvements:

- replaced NULL with 'data' in the second argument of the free_irq calls,
  which fixes problem on the module removal
- changed the order of checking for the platform_data and added
  checking for the -EPROBE_DEFER as spotted by Lars-Peter Clausen
- moved ak8975.txt out of staging as spotted by Jonathan Cameron
- modified header description in ak8975.txt
- renamed '0C' to '0c' in the examplary device node in ak8975.txt

Thanks,
Jacek Anaszewski
