After the WITH_QEMU_LOCK_GUARD macro is added, the compiler cannot identify
that the statements in the macro must be executed. As a result, some variables
assignment statements in the macro may be considered as unexecuted by the compiler.
The compiler showed warning:
hw/rdma/rdma_backend.c: In function ‘rdma_poll_cq’:
hw/rdma/rdma_utils.h:25:5: warning: ‘ne’ may be used uninitialized in this function [-Wmaybe-uninitialized]
25 | error_report("%s: " fmt, "rdma", ## __VA_ARGS__)
| ^~~~~~~~~~~~
hw/rdma/rdma_backend.c:93:12: note: ‘ne’ was declared here
93 | int i, ne, total_ne = 0;
| ^~
Add a default value for 'ne' to prevented the warning.
