Subject: [PATCH v3 1/6] iio: cros_ec: Accept -EOPNOTSUPP as 'not supported' error code
Date: Sun, 26 Jul 2020 15:00:56 -0700
Message-ID: <20200726220101.29059-2-linux@roeck-us.net> (raw)
In-Reply-To: <20200726220101.29059-1-linux@roeck-us.net>

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.
