diff --git a/tools/pci/pcitest.c b/tools/pci/pcitest.c index 0a1344c45213..59bcd6220a58 100644 --- a/tools/pci/pcitest.c +++ b/tools/pci/pcitest.c @@ -40,7 +40,7 @@ struct pci_test { static int run_test(struct pci_test *test) { - struct pci_endpoint_test_xfer_param param; + struct pci_endpoint_test_xfer_param param = {0}; int ret = -EINVAL; int fd;
The values in param may be random if they are not initialized, which may cause use_dma flag set even when "-d" option is not provided in command line. Initializing all members to 0 to solve this.
