[PATCH] extcon: Mark extcon_get_edev_name() function as exported symbol

[Mayank Rana]

extcon_get_edev_name() function provides client driver to request
extcon dev's name. If extcon driver and client driver are compiled
as loadable modules, extcon_get_edev_name() function symbol is not
visible to client driver. Hence mark extcon_find_edev_name() function
as exported symbol.
