From e8bac9e0647dd04c83fd0bfe7cdfe2f6dfb100d0 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Tue, 29 Jul 2008 12:52:20 -0500 Subject: [PATCH] [SCSI] scsi_transport_spi: fix oops in revalidate The class_device->device conversion is causing an oops in revalidate because it's assuming that the device_for_each_child iterator will only return struct scsi_device children. The conversion made all former class_devices children of the device as well, so this assumption is broken. Fix it.
