media: firewire: Using uninitialized values in node_probe()
If fw_csr_string() returns -ENOENT, then "name" is uninitialized. So
then the "strlen(model_names[i]) <= name_len" is true because strlen()
is unsigned and -ENOENT is type promoted to a very high positive value.
Then the "strncmp(name, model_names[i], name_len)" uses uninitialized
data because "name" is uninitialized.
