src/sys/dev/acpi: acpi.c
Log Message:
Remove PNP0C01 and PNP0C02 from the list of ignored HIDs (and CIDs).
Fixes PR kern/42937 from Ryo Onodera.
As acpi_match_hid() matches also "compatible IDs" (CIDs), we must be careful
when adding devices to this list. For example, the above PR revealed that
the following is a fairly typical way to define the HPET device:
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (_CID, EisaId ("PNP0C01"))
...
Arguably this is a BIOS bug, given that PNP0C01 and PNP0C02 should uniquely
identify a device (or a resource template) that has nothing to do with HPET.
