Subject: PCI: of: Ignore resources with failed translation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f134f25162e7174ebe63f8aa16810192606eb826;p=linux-beck.git

PCI: of: Ignore resources with failed translation

This patch allows PCI host controller to function even if part of resources
is unusable for some reason. An example is non-LPAE kernel on a machine
which has some 64-bit resources. Unusable resources will be just skipped
instead of a complete failure.
