[PATCH/RFC 07/17] iio: st_sensors: Use bitfield helpers

From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2021-11-22 15:55:53
Also in: alsa-devel, linux-aspeed, linux-clk, linux-gpio, linux-iio, linux-media, linux-mmc, linux-omap, linux-pm, linux-renesas-soc, lkml, netdev
Subsystem: iio subsystem and drivers, the rest · Maintainers: Jonathan Cameron, Linus Torvalds

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.
