viacam: Don't explode if pci_find_bus() returns NULL
In the unlikely case that pci_find_bus() should return NULL viacam_serial_is_enabled() is going to dereference a NULL pointer and blow up. Better safe than sorry, so be defensive and check the pointer. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
