You could use:

I guess we'd better just wait and see whether uninitialized_var()
survives before discussing your suggestion (see the thread starting at
https://lkml.org/lkml/2012/10/26/508 ).
Although this in the special QP data flow, I still prefer to avoid adding extra
code (even setting
initial values at procedure entry). The line above will also do the job.
"uninitialized_var"
is used elsewhere in the driver. See, for example, mlx4_ib_post_send() in the
same file (qp.c).
(replying to an e-mail of a few months ago)
If there are no further objections I'd like to see this patch to go
upstream. It fixes an annoying compiler warning and I don't think that
this patch has a negative performance impact.
Thanks,
Bart.
