From 9aa10e791c2b722cf166f46424a6a8364164fe12 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 29 Aug 2022 14:17:28 +0200 Subject: [PATCH] s390/delay: sync comment within __delay() with reality The comment within __delay() is outdated and does not reflect anymore what the function is doing. Therefore replace the comment.
