When fixing a kernel configuration warning, it is often necessary to
modify the kernel's meta-data and re-run the tools to update and
re-audit the config. This implies that the patch, config and audit
steps are run multiple times.
The tools had a bug that would incorrectly restore old meta-data
versus using updated configuration. Updating the kern-tools SRCREV
to fix the issue.
