Use the field_prep() helper, instead of open-coding the same operation. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Compile-tested only. Marked RFC, as this depends on [PATCH 01/17], but follows a different path to upstream. --- drivers/iio/common/st_sensors/st_sensors_core.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
