hah, right,
this is caused by commit a192a9580bcc41692be1f36b77c3b681827f566a,
which removes the "PREFIX" in include/acpi/acpi_bus.h
commit a192a9580bcc41692be1f36b77c3b681827f566a

ACPI: Move definition of PREFIX from acpi_bus.h to internal..h
Linux/ACPI core files using internal.h all PREFIX "ACPI: ",
however, not all ACPI drivers use/want it -- and they
should not have to #undef PREFIX to define their own.
Add GPL commment to internal.h while we are there.
This does not change any actual console output,
asside from a whitespace fix.

thanks for finding and fixing this.
thanks,
