Couple of comments:

- In extcon.c, line 560: 'state' is unused.

- extcon_set_property(edev, EXTCON_USB, EXTCON_USB_VBUS, 0);
  does not work. As written, it has to be something like:

  union extcon_property_value prop;
  ...
  prop.intval = vbus_state;
  extcon_set_property(edev, EXTCON_USB, EXTCON_USB_VBUS, prop);

- For USB, the state of EXTCON_USB, EXTCON_USB_HOST, and
EXTCON_DISP_DP tend to change at the same time, together with the
associated properties.
  It might be desirable to have an equivalent of extcon_sync_all(edev);

Thanks,
Guenter
