Subject: Print Root complex related registers on RCEC, too
X-Git-Tag: v3.6.3~41
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=7155d5104506e6459bb751f073a48eded9afae99;p=pciutils.git

Print Root complex related registers on RCEC, too

PCIe spec says root ports and root complex event collectors must implement
root CAP, STAT and CTRL registers, so call cap_express_root() not only for
PCI_EXP_TYPE_ROOT_PORT but also for PCI_EXP_TYPE_ROOT_EC.
