random: update comment from copy_to_user() -> copy_to_iter()
commit 63b8ea5e4f1a87dea4d3114293fc8e96a8f193d7 upstream. This comment wasn't updated when we moved from read() to read_iter(), so this patch makes the trivial fix. Fixes: 1b388e7765f2 ("random: convert to using fops->read_iter()") Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
