How is this "obvious"? I tried finding the specification and could not
see anything
to back up TIS 1.3 being only supported with TPM 1.3, or the existence of a
TPM 1.3 specification at all.
Please consider that not everyone reading this patch description is deeply
familiar with the details and explain exactly what the mistake is.

In a bug fix, try to always add a 'FIxes' tag such as 'Fixes: 0edbfea537d1
("tpm/tpm_tis_spi: Add support for spi phy")', and Cc everyone that was
involved in the original patch that introduced a bug so they can Ack or
Nak it.
