The drivers is in more or less good shape, conforms to the IIO ABI and none of
the default static code checker report any problems, so move it out of staging.

This patch fixes the issue with double minus in output when
reading channels from sysfs for IIO_VAL_INT_PLUS_MICRO and
IIO_VAL_INT_PLUS_NANO cases. Until this patch if val and val2
both are negatives output string contains "--" before
digits. It is result of "-%d..." in sprintf() format.

This patch adds IIO driver for APDS9300 ambient light sensor (ALS).

The driver allows to read raw data from ADC registers or calculate
lux value. It also can handle threshold interrupt.

Add a resource managed devm_iio_device_alloc()/devm_iio_device_free()
to automatically clean up any allocations made by IIO drivers,
thus leading to simplified IIO drivers code.
In addition, this will allow IIO drivers to use other devm_*() API
(like devm_request_irq) and don't care about the race between
iio_device_free() and the release of resources by Device core
during driver removing.

Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.
Also reorder those entries which weren't in alphabetical order yet.

Add a MODULE_DEVICE_TABLE in order to let hotplug mechanisms automatically

This makes it also possible to use the usual driver name instead of

This set is larger than I would like, partly due to my lack of review
time in the weeks before the merge window and partly because a
couple of large drivers and the subsystem as a whole seem to be
getting a lot more exposure and testing recently.
1) A long term bug in trigger handling gave a double free of the device.
2) Wrong return value handling means offsets are ignored in
iio_convert_raw_to_processed_unlocked.
3) The iio_channel_has_info utility function was incorrectly updated
during the recent info_mask split, this is now fixed.
4) mxs-lradc has a couple of little fixes.
5) A couple of missing .driver_module entries meant that drivers
could be removed from underneath their users.
6) Error path fixes for ad7303 and lis3l02dq.
7) The scale value for presure in the lps331ap driver was out by
a factor of 100.
