[PATCH 5.4 024/110] iio: adc: stm32-dfsdm: fix single conversion

[Greg Kroah-Hartman]

From: Olivier Moysan <olivier.moysan@xxxxxx>

commit dc26935fb60e8da8d59655dd2ec0de47b20d7d8f upstream.

Apply data formatting to single conversion,
as this is already done in continuous and trigger modes.

Fixes: 102afde62937 ("iio: adc: stm32-dfsdm: manage data resolution in trigger mode")
