16 years agosecurity: avoid calling a NULL function pointer in drivers/video/tvaudio.c

security: avoid calling a NULL function pointer in drivers/video/tvaudio.c

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.

[S390] Use s390_root_dev_* in kvm_virtio.

No need to define a static device for the kvm_s390 root device,
just use s390_root_dev_register().

This is needed for the bus_id rework
