From e7e3b9d23f3bc6774cce585ef4fcb02462e04065 Mon Sep 17 00:00:00 2001 From: Gwendal Grignou Date: Tue, 26 May 2020 21:35:17 -0700 Subject: iio: cros_ec: Reapply range at resume EC does not currently preserve range across sensor reinit. If sensor is powered down at suspend, it will default to the EC default range at resume, not the range set by the host. Save range if modified, and apply at resume.
