The reality is that 'ret' is initialized in every path through ath12k_qmi_load_file_target_mem() except one, the case where the input 'len' is 0, and hence the "while (remaining)" loop is never entered. But to make sure this case is also handled, add an initializer to the declaration of 'ret'. No functional changes, compile tested only.
