gio_match_device - Tell if an of_device structure has a matching gio_match structure : array of of device match structures to search in : the of device structure to match against

Used by a driver to check whether an of_device present in the system is in its list of supported devices.

gio_release_dev - free an gio device structure when all users of it are finished. : device that's been disconnected

Will be called only by the device core when all users of this gio device are done.
