2.27.0
This patch resolves the issue by reverting the above hunk, plus a fix to still build:
0001-pmbus-core-Remove-phase-paramter-from-pmbus_add_sens..txt
However, upstream has a patch that fixes it properly. It was added to stable in v5.7.8, so if we had waited a few more days we would have never seen this failure in the openbmc tree.
b4c8af4 is the upstream commit. ed0021d is the v5.7 stable commit.
This was fixed in openbmc by integrating the v5.7 stable fixes into dev-5.7.
