[PATCH 0/2] iio: adc: stm32-dfsdm: fix build dependencies

[Fabrice Gasnier]

This series fixes two build dependencies:
- IIO_BUFFER needs to be selected along with IIO_BUFFER_HW_CONSUMER
- IIO_TRIGGERED_BUFFER needs to be selected now that it supports triggered
  buffer mode.

[PATCH 1/2] iio: adc: stm32-dfsdm: fix unmet direct dependencies detected

[Fabrice Gasnier]

This fixes unmet direct dependencies seen when CONFIG_STM32_DFSDM_ADC
is selected:

WARNING: unmet direct dependencies detected for IIO_BUFFER_HW_CONSUMER
  Depends on [n]: IIO [=y] && IIO_BUFFER [=n]
  Selected by [y]:
  - STM32_DFSDM_ADC [=y] && IIO [=y] && (ARCH_STM32 [=y] && OF [=y] ||
    COMPILE_TEST [=n])

Fixes: e2e6771c6462 ("IIO: ADC: add STM32 DFSDM sigma delta ADC support")

[PATCH 2/2] iio: adc: stm32-dfsdm: fix triggered buffer build dependency

[Fabrice Gasnier]

This fixes build errors seen when CONFIG_STM32_DFSDM_ADC is set, as
stm32-dfsdm-adc driver now also relies on triggered buffer API:

Hmm. I wonder how we never got this one from a rand config.
Anyhow, give we are near the end of this cycle, I'll take this for
the next merge window rather than rushing it through.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

Thanks,

Jonathan
