4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann <arnd@xxxxxxxx> commit e36ae3439936e13c33f5841c7c2c1a9875acbb6d upstream. xencons_disconnect_backend() is only called from xen_console_remove(), which is conditionally compiled, so we get a harmless warning when CONFIG_HVC_XEN_FRONTEND is unset: hvc/hvc_xen.c:350:12: error: 'xen_console_remove' defined but not used [-Werror=unused-function] This moves the function down into the same #ifdef section to silence the warning.
