tpm_tis has a 'spare' entry in its device ID table for adding user-specified device IDs. This will be ignored by the driver matching logic, but modpost turns it into:
alias: acpi*::*
alias: pnp:d*
This seems to result in the driver being loaded on almost all PCs.
Change do_pnp_device_entry() to stop if it finds such an entry,
similarly to do_usb_entry_multi().
