[PATCH] parport_pc: Limit the number of PCI BAR pairs to 2

From: Maciej W. Rozycki
Date: Wed Nov 16 2022 - 16:36:52 EST


Decrease the number of PCI BAR pair slots allocated for port subdrivers
from 4 to 2 as none wants more than 2 at this time, reducing the memory
footprint a little. No functional change.
