Configuration cid=88301: outlier?

[acherm]

Configuration cid=88301 has AIC79XX_BUILD_FIRMWARE=y

for op in get_configuration_file(88301).splitlines():
    #print(op)
    if ("AIC79XX_BUILD_FIRMWARE=y" in op):
        print(op)
    if ("PREVENT" in op):
        print(op)

Getting configuration file of cid= 88301
# CONFIG_PREVENT_FIRMWARE_BUILD is not set
CONFIG_AIC79XX_BUILD_FIRMWARE=y

but there is no build failure in the database...
Looking at the log:

it seems there are warnings... but no real error or failure.

It sounds an outlier.
I don't get:

• why we don't notice it previously during data analysis
• why there is no build failure despite AIC79XXX

Any idea?
