The driver needs that 'more' to reach the lock registers for the flash
chip. If it's being used for other things, shouldn't the
request_region() fail?
On a vaguely related note, there's a lot to be said for _not_ using the
standard PCI driver setup on the BIOS flash drivers, and going back to
having them manually loaded rather than being automatically loaded
whenever the appropriate southbridge is present.
It would be nicer if the only people who have write access to their BIOS
flash are the ones who _really_ wanted it.
