UGh, the test-robot gave the same errors for v1 of this patch-set; and I checked,
but I could not find the problem. Since there was some time between v1 and v2
I assumed that I had already fixed this in my local tree, but I now see that
this is caused by a bug in the #else block of the
#ifdef CONFIG_ACPI
#else
#endif

in this patch. I will submit a v3 of this patch-set fixing this.

Hans
