From 6db07b6336589ff480528173e41f8f6af3f0097f Mon Sep 17 00:00:00 2001 From: Bill Richardson Date: Wed, 18 Jun 2014 11:14:05 -0700 Subject: mfd: cros_ec: Check result code from EC messages Just because the host was able to talk to the EC doesn't mean that the EC was happy with what it was told. Errors in communincation are not the same as error messages from the EC itself. This change lets the EC report its errors separately.
