The compilation with gcc-6.3.0 and EXTRA_CFLAGS=-Og gives the following
error:
CC eal_pci_uio.o
eal_pci_uio.c: In function ‘pci_get_uio_de ’:
eal_pci_uio.c:221:9: error: ‘uio_num’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
return uio_num;
^~~~~~~
This is a false positive: gcc is not able to see that when e != NULL,
uio_num is always set. Fix the warning by initializing uio_num to -1,
and by the way, change the type to int.
