The 'single_cpu' local variable is assigned by asoc_simple_parse_dai() and later used in a asoc_simple_canonicalize_cpu() call, assuming the entire function did not exit on errors.
However the first function returns 0 if passed device_node is NULL, thus leaving the variable uninitialized and reporting success.
