Bug description:
[Impact]
The fail check in the end of powerpc/eeh/eeh-basic.sh script will complain
about "unexpected operator"
This is caused by the following line in the script:
$ test "$failed" == 0
/bin/sh: 4: test: 0: unexpected operator
[Fix]
* 3db380570af705 ("selftests/powerpc: Make the test check in eeh-basic.sh
posix compliant")
This is affecting F/G/H and can be cherry-picked for all of them.
[Test case]
Run the eeh-basic.sh script in tools/testing/selftests/powerpc/eeh/
This error message should be gone.
[Where problems could occur]
This fix is limited to PowerPC testing tool, it's unlike to cause any issue.
