Subject: PCI: pcie portdriver: initialize returned value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bf164410d08dc83df416e3a6a43ab29bf88890ed;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.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.
