[PATCH 0/5] iio: device-managed conversions with devm_iio_map_array_register()

This change introduces a devm_iio_map_array_register() variant for the
iio_map_array_register() function.

And converts 4 drivers to full device-managed.
These 4 drivers only call iio_map_array_unregister() and
iio_device_unregister() in their remove hooks.

These 4 drivers should make a reasonably good case for introducing this
devm_iio_map_array_register() function.

There are 7 more drivers that would use the devm_iio_map_array_register()
function, but they require a bit more handling in the remove/unwinding
part.
So, those 7 are left for later.

Alexandru Ardelean (5):
iio: inkern: introduce devm_iio_map_array_register() short-hand
function
iio: adc: intel_mrfld_adc: convert probe to full device-managed
iio: adc: axp288_adc: convert probe to full device-managed
iio: adc: lp8788_adc: convert probe to full-device managed
iio: adc: da9150-gpadc: convert probe to full-device managed
