From 93e1b7d42e1edb4ddde6257e9a02513fef26f715 Mon Sep 17 00:00:00 2001 From: Kylene Jo Hall Date: Sat, 22 Apr 2006 02:39:52 -0700 Subject: [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.
