SCSI: scsi_transport_spi: fix oops in revalidate
commit e8bac9e0647dd04c83fd0bfe7cdfe2f6dfb100d0 upstream
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.
