Subject: Re: [bug report] vDPA/ifcvf: implement shared IRQ feature

Message-ID: <20220315092117.GV3315@kadam> (raw)

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;
      ^~~~~~~~~~~~~

regards,
dan carpenter
