Today's -next fails to boot on a couple of apq8064 boards:
arm: qcom_defconfig: gcc-8: qcom-apq8064-cm-qs600: 1 failed lab qcom-apq8064-ifc6410: 1 failed lab
In both cases it looks like the error handling when we fail to get the firmware for the GPU is broken, we get a crash in the initialization code shortly after failing to load some firmware:
