Applied. Whilst doing this I note that I'm getting a few sparse
warnings for this driver that would be nice to clean up...

CHECK drivers/iio/adc/stm32-dfsdm-adc.c
drivers/iio/adc/stm32-dfsdm-adc.c:503:21: warning: expression using sizeof(void)
drivers/iio/adc/stm32-dfsdm-adc.c:503:21: warning: expression using sizeof(void)

Which is mystifying at first glance... Something deep and dirty in the min macro
but I can't see what..

drivers/iio/adc/stm32-dfsdm-adc.c:680:5: warning: symbol 'stm32_dfsdm_get_buff_cb' was not declared. Should it be static?
drivers/iio/adc/stm32-dfsdm-adc.c:703:5: warning: symbol 'stm32_dfsdm_release_buff_cb' was not declared. Should it be static?

Are rather more obvious
