commit d3042cbe84a060b4df764eb6c5300bbe20d125ca upstream.
The error path of copying the old config used the wrong variable in the error message:
$ mkdir /tmp/build $ ./tools/testing/ktest/config-bisect.pl -b /tmp/build config-good /tmp/config-bad $ chmod 0 /tmp/build $ ./tools/testing/ktest/config-bisect.pl -b /tmp/build config-good /tmp/config-bad good cp /tmp/build//.config config-good.tmp ... [0 seconds] FAILED! Use of uninitialized value $config in concatenation (.) or string at ./tools/testing/ktest/config-bisect.pl line 744. failed to copy to config-good.tmp
When it should have shown:
failed to copy /tmp/build//.config to config-good.tmp
