This is from 201811 github prebuilt binary:
https://sonic-jenkins.westus2.cloudapp.azure.com/job/broadcom/job/buildimage-brcm-201811/152/artifact/target/sonic-broadcom.bin

The issue happens on master too. please check the serial number for more HW information.

As you can probably see, "gpiochip452" was the one screwed up the PSU gpio base.
