Just out of curiosity, did you find this by some tool? If so, can you
please let me know the tool name so that I can avoid such problems in
the future? Thanks.

No, not found by tool. I was working on a patch set which tried to
introduce a new acpi bus type [1], so I greped the usage of
"struct acpi_bus_type" then found this issue :)
