What I really want is to re-enable GCC's uninitialized variable warning.
$ rm drivers/vdpa/ifcvf/ifcvf_main.o
$ make W=2 drivers/vdpa/ifcvf/ifcvf_main.o
It prints a ton of output but this is the relevant bit.
drivers/vdpa/ifcvf/ifcvf_main.c: In function ‘ifcvf_vdpa_set_status’:
drivers/vdpa/ifcvf/ifcvf_main.c:291:6: warning: ‘config_vector’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
int config_vector, ret;
^~~~~~~~~~~~~
