[PATCH v1 1/1] iio: adc: ad7173: Fix digital filter configuration
From: Marcelo Schmitt
Date: Wed Sep 16 2026 - 13:15:24 EST
Filter enable and filter type selection masks were swapped on data
preparation for filter configuration register write. Use the correct masks
to set each property of post filter configuration.
Fixes: bb688cd9f772 ("iio: adc: ad7173: support changing filter type")
