Subject: [PATCH] iio: cros_ec: set calibscale for 3d MEMS to unit vector
Date: Mon, 19 Aug 2019 22:10:29 -0700 [thread overview]
Message-ID: <20190820051029.118905-1-gwendal@chromium.org> (raw)
By default, set the calibscale vector to unit vector.
It prevents sending 0 as calibscale when not initialized.
Signed-off-by: Gwendal Grignou <gwendal@chromium.org>
