Peter Huewe (3):

This patch changes the call of tpm_transmit by supplying the size of the userspace buffer instead of TPM_BUFSIZE

This patch fixes information leakage to the userspace by initializing the data buffer to zero

Since the buffer might contain security related data it might be a good idea to zero the buffer after we have copied it to userspace.

Given the nature of these changes, they should go to current linus as bug fixes.
