Attribute "kb_wake_angle" in /sys/<cros_ec hw path>/chromeos/cros_ec, used to set at which angle the embedded controller must wake up the host, is only set when there is at least 2 accelerometers in the chromebook.
The detection of these sensors is done in cros_ec_sensorhub, driver that can be probed after the cros_ec_sysfs driver that sets the attribute. Therefore, we need to upgrade the cros_ec sysfs groups in the sensorhub probe routine. The first patch cleans up cros_ec_sysfs by using .dev_groups driver field, the second patch fixes the problem.
