This fixes the problem in the same way the generic PCIe AER code
(in
drivers/pci/pcie/aer/aerdrv_core.c) does. It makes the EEH code
hold
the device_lock() before performing the driver EEH callbacks. This
ensures either the callbacks are no longer register, or if they are
registered the driver will not be removed from underneath us.

Generally ok, minor nits though and do we want a CC stable ?

I definitely think this should go to stable.
