Subject: acpi: fix single linked list manipulation
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
Fix single linked list manipulation for sub_driver. If the remving entry
is not on the head of the sub_driver list, it goes into infinate loop.
Though that infinite loop doesn't happen. Because the only user of
acpi_pci_register_dirver() is acpiphp.
