GCC now reports uninitialized warnings from function return values. ../lib/netdev-dpdk.c: In function 'netdev_dpdk_mempool_configure': ../lib/netdev-dpdk.c:964:22: warning: 'dmp' may be used uninitialized [-Wmaybe-uninitialized] 964 | dev->dpdk_mp = dmp; | ~~~~~~~~~~~~~^~~~~ ../lib/netdev-dpdk.c:854:21: note: 'dmp' was declared here 854 | struct dpdk_mp *dmp, *next; | ^~~
NB: this looks like a false positive, gcc 13 probably fails to see the link between reuse and dmp in dpdk_mp_get().
