Subject: [PATCH 1/3] PA-RISC: handle pushd failure
from https://github.com/lyonel/lshw/pull/89
When /sys/devices/parisc does not exist, any directory with a name consisting of only numbers in current working directory was being interpreted as a device, for example:
krzys_h@krzysh-laptop:/mnt/ramdisk $ ls /sys/devices/parisc
ls: cannot access '/sys/devices/parisc': No such file or directory
krzys_h@krzysh-laptop:/mnt/ramdisk $ mkdir 13374242
krzys_h@krzysh-laptop:/mnt/ramdisk $ sudo lshw | grep 13374242 -B3 -A3
width: 64 bits
clock: 1600MHz (0.6ns)
*-generic UNCLAIMED
physical id: 13374242
bus info: parisc@13374242
*-pci
description: Host bridge
product: Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller
This commit fixes that by properly checking the return value from pushd.
