From f8c2c4202d86e14ca03b7adc7ebcb30fc74b24e1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 15 May 2006 20:57:30 +0900 Subject: [PATCH] [PATCH] libata: fix ->phy_reset class code handling in ata_bus_probe() ata_bus_probe() doesn't clear dev->class after ->phy_reset(). This can result in falsely enabled devices if probing fails. Clear dev->class to ATA_DEV_UNKNOWN after fetching it.
