From 1716420e8de2705cd16905134d1eaeda94272a17 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sat, 22 Aug 2020 08:08:51 -0700 Subject: iio: cros_ec: Accept -EOPNOTSUPP as 'not supported' error code A follow-up patch will extend the number of errors reported by cros_ec_cmd_xfer_status(). Specifically, the function will return -EOPNOTSUPP if a command is not supported by the EC. Prepare for it.
