SubjectRe: [PATCH 6 of 6] tpm: move infineon driver off pci_dev
From
Date
Matthieu,

Thanks for the comments. I mistakenly generated this patch which
overwrote some of the changes that Marcel had submitted. I am working
on going back to the pnp names and I'll additionally take these comments
into consideration. Please hold off on applying this patch.

Thanks,
Kylie
