From 6dffaf61e22d21e539ae7e30c2e33e41230c3d52 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 23 May 2007 11:58:52 +0200 Subject: [PATCH] libata: -ENODEV during prereset isn't an error During prereset, -ENODEV return from ata_wait_ready() is not an error. This causes unnecessary bug message on controllers which uses 0xff to indicate empty port. Fix it.
