Hi Anuj, Hi Bruce,

These patches have now been merged on master, so we had build failures
for a few days now on the said recipes.

mesa-intel:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/41/builds/1426

meta-virt:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/89/builds/1439

Best regards,
Mathieu
