PNPACPI: cope with invalid device IDs

PNPACPI: cope with invalid device IDs

commit 420a0f66378c84b00b0e603e4d38210102dbe367 upstream.

If primary ID (HID) is invalid try locating first valid ID on compatible
ID list before giving up.

This helps, for example, to recognize i8042 AUX port on Sony Vaio VPCZ1
which uses SNYSYN0003 as HID. Without the patch users are forced to
boot with i8042.nopnp to make use of their touchpads.
