Fabrice Gasnier ed582db639 iio: adc: stm32-dfsdm: include stm32-dfsdm-adc.h 
Fix the following sparse warnings:
  CHECK   drivers/iio/adc/stm32-dfsdm-adc.c
symbol 'stm32_dfsdm_get_buff_cb' was not declared. Should it be static?
symbol 'stm32_dfsdm_release_buff_cb' was not declared. Should it be static?

BTW, move interrupt.h to sort headers alphabetically.

IIO: ADC: add stm32 DFSDM support for PDM microphone 
This code offers a way to handle PDM audio microphones in
ASOC framework. Audio driver should use consumer API.
A specific management is implemented for DMA, with a
callback, to allows to handle audio buffers efficiently.
