The cdns3_host_init() function is declared in host-export.h but host.c does not include it. Add the include to have the declaration present (and remove the declaration of cdns3_host_exit which is now static). Fixes the following sparse warning: drivers/usb/cdns3/host.c:58:5: warning: symbol 'cdns3_host_init' was not declared. Should it be static?
