What is tpm_infineon and why does it fix my laptop suspend problem?

[AmagicalFishy]

I'm using Ubuntu 14.04 and my laptop (HP8460P) recently stopped suspending. I'm not sure when exactly this happened, or what prompted it. After toying around a little, I've traced everything to a module called tpm_infineon.

If I enter the command:

sudo modprobe -r tpm_infineon

I'm able to suspend successfully and normally.

What is tpm_infineon and why might it be screwing up my laptop's suspend ability?

The dmesg lines that lead me to this module were:

[ 127.404041] tpm_inf_pnp 00:03: saving TPM state
[ 127.425528] tpm_inf_pnp 00:03: Timeout while clearing FIFO
[ 127.425529] tpm_inf_pnp 00:03: error while saving TPM state
