Describe exactly what you mean instead of "faster way" and "multiple
bytes".

You are missing commas in the short summary message when you list bunch
of things.

We prefer "tpm:" instead of "char: tpm:" as the tag for this subsystem.
You are also implying that this would be something global for the TPM
driver whereas it is only scoped to tpm_tis:

Rephrase it something like:

  "tpm: tpm_tis: Make 32-bit reads and writes optional"

Please, first, take this away:

"
This commit is based on previous work by Alexander Steffen.

Signed-off-by: Amir Mizinski <amirmizi6@...il.com>
"

Then, replace it with:

Co-developed-by: Alexander Steffen <Alexander.Steffen@...ineon.com>
Signed-off-by: Alexander Steffen <Alexander.Steffen@...ineon.com>
Signed-off-by: Amir Mizinski <amirmizi6@...il.com>
