security: avoid calling a NULL function pointer in drivers/video/tvaudio.c
commit 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1 upstream
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.
