Subject: [PATCH/RFC 09/17] iio: imu: st_lsm6dsx: Use bitfield helpers
Date: Mon, 22 Nov 2021 16:54:02 +0100 [thread overview]
Message-ID: <9b479b1a72c95c1c0d52b1782037bcaab7df856b.1637592133.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1637592133.git.geert+renesas@glider.be>
Use the field_prep() helper, instead of defining a custom macro, or
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
