security: avoid calling a NULL function pointer in drivers/video/tvaudio.c
From: Arjan van de Ven <arjan@linux.intel.com>
NULL function pointers are very bad security wise. This one got caught by
kerneloops.org quite a few times, so it's happening in the field....
Fix is simple, check the function pointer for NULL, like 6 other places
in the same function are already doing.
