It is polled after the timer expires in tpm_tis_send_data, but not in
tpm_tis_send, and the return value is used in tpm_tis_send...

...so with the other patch applied too, the output is:
[ 1.464217] tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16)
[ 3.570836] tpm_tis 00:08: tpm_transmit: tpm_send: error -62
[ 3.660885] tpm_tis 00:08: [Firmware Bug]: TPM interrupt not working,
polling instead
Much better! Any thoughts before I proceed?
