        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.
