From 4aa9ab67fb9c0dfdb1692f4ec413120832a22ddc Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 12 Mar 2007 17:24:08 +0900 Subject: [PATCH] libata: don't whine if ->prereset() returns -ENOENT ->prereset() returns -ENOENT to tell libata that the port is empty and reset sequencing should be stopped. This is not an error condition. Update ata_eh_reset() such that it sets device classes to ATA_DEV_NONE and return success in on -ENOENT. This makes spurious error message go away.
