[tpmdd-devel] TPM atmel and nsc should use PNP

[Bjorn H. <bjo...@hp...>]

tpm_infineon.c and tpm_tis.c use pnp_register_driver() to bind to
devices with matching PNP IDs.  That seems like the right way to
do it.

But tpm_atmel.c and tpm_nsc.c just blindly poke around looking for
their device.  That seems wrong.  Is there some reason they can't
use pnp_register_driver() also?  I'd be glad to send a patch to
fix this if somebody knows the appropriate list of PNP IDs that
these drivers should claim.

I like the recent tpm_tis.c changes to give a hook for use when
ACPI doesn't correctly describe the TPM device.  That will give
manufacturers a hint that they're doing something wrong.
