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)

|
This commit fixes that by properly checking the return value from pushd.
