Sorry for confusing. I am really new to kernel community! I should just add the tag 'Cc: stable@vger.kernel.org' , not really cc to stable@vger.kernel.org sorry for this!
Best Regards!

From commit 6915564dc5a8 ("ACPI: OSL: Change the type of
acpi_os_map_generic_address() return value"), acpi_os_map_generic_address() will return logical address or NULL for error, but for ACPI_ADR_SPACE_SYSTEM_IO case, it should be also return 0, as it's a normal case, but now it will return -ENXIO. so check it out for such case to avoid einj module initialization fail.

I'm confused as to what you are asking us to do with this patch? Have you read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly?
thanks,
