You don't, my mistake. My build bot runs with 6e8d666e9253 ("Disable
"maybe-uninitialized" warning globally") disabled, and I had
assumed that Linus left the warning enabled with "make W=1", but
that was incorrect as Trond Myklebust also pointed out.
You still get the warning with "make EXTRA_CFLAGS=-Wmaybe-uninitialized",
which of course nobody normally does.
I'll try to come up with a patch to enable the warning in the W=1
level in the same conditions that used to be enabled up to v4.7.
