Subject: extcon: Mark extcon_get_edev_name() function as exported symbol
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=995bb1092326b8ba8fa29456c334ac6a49765ccd;p=linux.git

extcon: Mark extcon_get_edev_name() function as exported symbol

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.
