I am confused. Looking at that bunch of ifs, acpi_is_video_device returns 1
for a match and 0 for no match. acpi_bay_match returns 0 for a match and
-ENODEV for no match, which just happens to work with the ACPI_SUCCESS macro.
acpi_dock_match returns ACPI error codes. Each of the three existing tests has
different return value semantics, so it is not clear to me which one I should
use.

I didn't think it was correct for my probe function to use the ACPI_STATUS
macro unless it returned ACPI error codes... which it does not. -ENODEV seemed
appropriate for "no device found".

Is it desirable to clean them all up to follow the same convention?
