Some functions in the au0828 driver are only used when CONFIG_MEDIA_CONTROLLER
is enabled, and otherwise defined as empty functions:
media/usb/au0828/au0828-core.c:208:13: error: 'au0828_media_graph_notify' defined but not used [-Werror=unused-function]
media/usb/au0828/au0828-core.c:262:12: error: 'au0828_enable_source' defined but not used [-Werror=unused-function]
media/usb/au0828/au0828-core.c:412:13: error: 'au0828_disable_source' defined but not used [-Werror=unused-function]
This moves the #ifdef so the entire definitions are hidden in this case.
