Any thoughts on this change?
Thanks.

context with the state of in-flight handlers and the driver
structures associated with pci_dev. The contet outlives both
the structs and the pci_dev.

This patch disables pcie error handling early in
qla2x00_disable_board_on_pci_error and in other paths that remove
those structs.

occasionally deadlocks.
Thus, removing configfs_depend_item calls does not break anything
and fixes the deadlock problem.

driver (like qla2xxx) itself; it is safe to drop the module reference
at that time.

Thanks, James. The idea of cutting communications with Scsi_Host at
bsg_unregister_queue(..) time and leaving bsg_class_device to
its own fate makes a lot of sense, conceptually. But there are
implementation issues that are difficult to work around.
