Subject: parport_pc: Limit the number of PCI BAR pairs to 2
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=96b45776995653a4971329c7f62ff6aa324027a2;p=linux.git

parport_pc: Limit the number of PCI BAR pairs to 2

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.
