We treat all WARN_QA as ERROR_QA by adding this line to the local.conf

ERROR_QA:append = " ${WARN_QA}"

In this case it would be the same as moving patch-fuzz into the ERROR_QA list.


When there are patch-fuzz QA errors the build correctly fails however not before sstate is populated. Subsequent builds will then pass using the stored sstate entries.


This patch is based on dunfell but almost identical patches could be applied to main. Other QA checks follow this same pattern checking for qa_sane before calling bb.fatal.
