commit 409bf7f8a02ef88db5a0f2cdcf9489914f4b8508 upstream.
In eeh_reset_device(), we take the pci_rescan_remove_lock immediately after
after we call eeh_reset_pe() to reset the PCI controller. We then call
eeh_clear_pe_frozen_state(), which can return an error. In this case, we
bail out of eeh_reset_device() without calling pci_unlock_rescan_remove().
Add a call to pci_unlock_rescan_remove() in the eeh_clear_pe_frozen_state()
error path so that we don't cause a deadlock later on.

It seems that something in your scripts munged the apostrophe in the
summary line when generating these emails. Though it looks fine in the
actual tree.
