From a1541d5af66d02426655b1498f814c52347dd7d3 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Thu, 9 Jun 2005 17:21:28 -0700 Subject: [PATCH] [SCSI] qla2xxx: Pull-down scsi-host-addition to follow board initialization. Return to previous held-logic of calling scsi_add_host() only after the board has been completely initialized. Also return pci_*() error-codes during probe failure paths. This also corrects an issue where only lun 0 is being scanned for a given port.
