From 2a81e813141ea5d26ff1edb4241033e14bb507fb Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Mon, 20 Jun 2022 11:03:48 +0200 Subject: [PATCH] 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.
