linux-next: build warning after merge of the random tree

Hi Ted,

[This actually appeared yesterday, but I missed it, sorry.]

After merging the random tree, today's linux-next build (x86_64
allnoconfig) produced this warning:

drivers/char/random.c:318:12: warning: 'random_min_urandom_seed' defined but not used [-Wunused-variable]
 static int random_min_urandom_seed = 60;
            ^

Introduced by commit

  43d8a72cd985 ("random: remove variable limit")

I understand why it is left there, but it would be nice if this warning
could be removed.
