Subject: ia64/PCI: Clear host bridge aperture struct resource
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=da104919059bd89dc77a77d74b0fb289384ce9b1;p=linux-beck.git

ia64/PCI: Clear host bridge aperture struct resource

Use kzalloc() so the struct resource doesn't contain garbage in
fields we don't initialize.
