Subject: random: update comment from copy_to_user() -> copy_to_iter()
From: Jason A. Donenfeld <Jason@xxxxxxxxx>
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()")
