From 2061a47a9b9530a9523e51167c996307db951c31 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 12 Mar 2006 00:57:39 +0900 Subject: [PATCH] [PATCH] libata: fix missing classes[] initialization in ata_bus_probe() ata_bus_probe() didn't initialize classes[] properly with ATA_DEV_UNKNOWN. As ->probe_reset() is allowed to leave @classes alone when no device is present, this results in garbage class values. ATM, the only affected driver is ata_piix.
