When cros_ec_sysfs probe is called before cros_ec_sensorhub probe
routine, the |kb_wake_angle| attribute will not be displayed, even if
there are two accelerometers in the chromebook.
Call sysfs_update_group() when accelerometers are enumerated if the
cros_ec sysfs attributes group has already been created.
Fixes: d60ac88a62df ("mfd / platform / iio: cros_ec: Register sensor through sensorhub")

This is odd, the platform/driver core should be creating these files,
you should never have to do this "by hand". If you do it this way, you
are racing with userspace and loosing.
Please set the dev_groups field in the driver structure to be this group
and then all will be fine automatically.

This should not be needed.
