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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Ted,

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

drivers/char/random.c: In function 'SYSC_getrandom':
drivers/char/random.c:1526:6: warning: unused variable 'r' [-Wunused-variable]
  int r;
      ^

Introduced by commit 386474e168a8 ("random: introduce getrandom(2) system call").

Cheers,
Stephen Rothwell                    sfr@xxxxxxxxxxxxxxxx
