PS3, Line 122: // FIXME: Fix chipset_enable.c usage and remove pcidev_set_pacc().
Even if `pacc` no longer has global visibility, it's still global state. To remove `pcidev_set_pacc()`, the alternative `struct pci_access` used in chipset_enable.c should be passed to the functions that need it by parameter.
