Subject[PATCH 4.19 129/276] iio: adc: stm32-dfsdm: fix unmet direct dependencies detected
Date
[ Upstream commit ba7ecfe43d6bf12e2aa76705c45f7d187ae3d7c0 ]

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")
