Subject: PCI: don't dump resource when bus resource flags indicates unused
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7c9342b8dd1a32386fc32bffb9eedebbfe264763;p=linux-beck.git

PCI: don't dump resource when bus resource flags indicates unused

Don't print out resources without flags to avoid cluttering up the debug
output.
