[PATCH] tpm: add HID module parameter
I recently found that not all BIOS manufacturers are using the specified
generic PNP id in their TPM ACPI table entry. I have added the vendor
specific IDs that I know about and added a module parameter that a user can
specify another HID to the probe list if their device isn't being found by the
default list.
