Subject: PCI: pcie portdriver: initialize returned value
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bf164410d08dc83df416e3a6a43ab29bf88890ed;p=deliverable%2Flinux.git

PCI: pcie portdriver: initialize returned value

The pcie protdrv status can be returned uninitialized,
if there are no children under a device. This leads to
bad responses downstream. Fix this.
