From 9ce41aed0d392246eb788786253f242e829fd5e1 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 28 Mar 2010 18:58:28 -0700 Subject: [PATCH] Revert "ide: skip probe if there are no devices on the port (v2)" This reverts commit a20b2a44eca52818ef52a94959480b7e6ea2f528. As requested by David Fries. This makes CDROMs which are slave drives on a ribbon without a master disappear and causes other similar kinds of badness. Signed-off-by: David S.
